Powerpoint presentation in DNA of living organisms
DNA is contained within the nucleus of cells. It is composed of nucleotides, which each contain a phosphate group, a sugar (deoxyribose), and one of four nitrogenous bases (adenine, guanine, cytosine, thymine). The bases bond together in pairs - adenine bonds with thymine, and cytosine bonds with guanine. Millions of these paired nucleotides bond together to form the signature double helix structure of DNA, with the bases on the inside and the sugar-phosphate backbones on the outside. This double helix structure allows DNA to be tightly packed inside cells.
Exploring DNA Lesson Plan
This lesson plan explores the structure and function of DNA through building a 3D model and extracting DNA from cheek cells. Students first create a DNA model using candy and toothpicks to represent nucleotides and base pairing. Next, they purify DNA from their own cheek cells using a kit. The extraction involves breaking open cells, precipitating DNA with alcohol and salt, and visualizing the extracted DNA. The lesson aims to give students hands-on experience visualizing key characteristics of DNA.

Dna intro
DNA stands for deoxyribose nucleic acid and is present in the nucleus of all cells in living organisms. It controls the chemical changes and development of cells, determining the type of cell (muscle, blood, etc.) and organism (plant, animal, etc.) produced. DNA is a long molecule composed of nucleotides, which each consist of a deoxyribose sugar, phosphate group, and organic base. The bases adenine, cytosine, guanine, and thymine combine in specific pairing between strands to form the double helix structure of DNA.
Dna struture
DNA contains the genetic instructions for life and is located in the nucleus of cells. It has a double helix structure with two strands twisted together like a ladder. The backbone is made up of alternating phosphate and deoxyribose sugars, while the rungs are nitrogenous bases that form hydrogen bonds between the strands in a specific pattern - adenine pairs with thymine and cytosine pairs with guanine. This ensures DNA can store and replicate the code of life.
Daily Lesson Plan in Science 10 (Nucleic Acid)
This daily lesson plan outlines a science class that will teach 10th grade students about nucleic acids. The lesson will begin with an activity to review carbohydrates and an introductory puzzle. Students will then work in groups to differentiate between DNA and RNA using pictures and descriptions. They will discuss the structures, sugars, bases, and functions of DNA and RNA. An nucleic acid song will be used to generalize learning. The lesson will conclude with a multiple choice assessment and an assignment on lipids and proteins. The teacher will reflect on student understanding and require additional activities as needed.
Dna first class
DNA is made up of nucleotides linked together by covalent bonds to form a single or double strand. Each nucleotide contains a nitrogenous base (adenine, guanine, cytosine or thymine), a sugar (deoxyribose) and a phosphate group. The bases on one strand form hydrogen bonds with complementary bases on another strand to form the famous double helix structure. Rosalind Franklin's X-ray crystallography photos and the work of Watson and Crick revealed that DNA has a double helix structure with the bases paired inside and the sugar-phosphate backbone on the outside.

Rosalind Franklin and Maurice Wilkins discovered the basic structure of DNA through X-ray diffraction images in 1950. In 1953, Watson and Crick used this evidence along with other research to determine that DNA has a double helix structure with nucleotides as monomers. DNA replicates through the unwinding of the double helix, exposing the nucleotides to pair with free floating nucleotides in the cell to form two identical DNA molecules.

The DNA double helix structure has these nucleotides bonded together in base pairs, with adenine bonding with thymine and guanine bonding with cytosine. DNA replication is the process where an existing DNA double helix unwinds and each strand serves as a template to produce a complementary new strand, resulting in two identical DNA molecules.
Dna millionaire review2
This document provides a 15 question quiz about DNA and genetics. It tests knowledge about the structure of DNA, including that it is made up of deoxyribonucleic acid, contains the sugar deoxyribose, and has paired bases of adenine-thymine and cytosine-guanine. It also covers topics like mutations, the double helix shape, differences between DNA and RNA like RNA containing ribose not deoxyribose, and that Watson and Crick discovered the structure of DNA. The quiz concludes that small amounts of DNA can also be found in mitochondria in addition to the nucleus.
STRUCTURE OF DNA AND TYPES OF DNA
There are three main types of DNA structures: A-DNA, B-DNA, and Z-DNA. Watson and Crick proposed the classic B-DNA model in 1953 which consists of two antiparallel polynucleotide chains coiled around the same axis to form a right-handed double helix. The purines and pyrimidines on each strand face inward and pair with each other through hydrogen bonding according to base pairing rules, with two hydrogen bonds between adenine and thymine and three between cytosine and guanine.
The Structure of DNA
DNA is composed of nucleotides that form a double helix structure with a phosphate-sugar backbone and paired nitrogenous bases inside. Watson and Crick determined that DNA has a double helix structure with A pairing with T and C pairing with G, allowing the molecule to reliably replicate, which built upon prior work by Franklin and Chargaff.
Biomol 4-asam nukleat
Friedrich Miescher isolated nuclein from cell nuclei in 1869. Nuclein was later called nucleic acid and shown to have acidic properties. There are two types of nucleic acids: DNA and RNA. DNA contains the genetic instructions and is found in the cell nucleus. RNA is found throughout the cell and is involved in carrying out the instructions specified by DNA. The structure of DNA was elucidated by Watson and Crick in 1953, revealing its double helix structure with two antiparallel strands bonded together via complementary nucleotide base pairing of A=T and C=G.

DNA has a double helix structure composed of nucleotides with deoxyribose sugar and bases of adenine, guanine, cytosine and thymine. DNA stores the genetic information in cells and determines the structure of proteins. Applications of understanding DNA include producing insulin, growth hormones and vaccines using recombinant DNA technology.
Dna structure1
The document discusses the structure and composition of DNA. It explains that DNA contains the blueprint of life in the form of instructions for making proteins. DNA has a double helix shape with two strands coiled around each other. Each strand consists of repeating nucleotide units containing a phosphate, deoxyribose sugar, and one of four nitrogenous bases: adenine, guanine, cytosine, or thymine. The bases on each strand bond with each other through hydrogen bonds, with adenine bonding only to thymine and cytosine bonding only to guanine. This ensures the fidelity of DNA replication and transmission of genetic information from parent cells to daughter cells.

DNA contains the genetic instructions for living organisms. It exists as a double helix structure with two strands bonded together via complementary base pairing between adenine and thymine, and cytosine and guanine. James Watson and Francis Crick discovered the double helix structure of DNA in 1953. DNA is found within the nucleus of cells in structures called chromosomes and carries the code for inheritable traits by way of genes.
01 The Structure and Replication of DNA
This document discusses the structure and replication of DNA. It describes that DNA is made up of nucleotides containing nitrogen bases, pentose sugars, and phosphate groups. The bases adenine, guanine, cytosine, and thymine make up DNA, with adenine pairing with thymine and cytosine pairing with guanine. DNA exists as a double helix with two polynucleotide strands running in opposite directions and held together by hydrogen bonds between complementary bases. During DNA replication, the double helix unwinds and each strand serves as a template for synthesis of a new complementary strand, resulting in two identical DNA molecules each with one original and one new strand.
Introduction to DNA
DNA is made up of nucleotides that contain deoxyribose, phosphates, and one of four nitrogenous bases: adenine, guanine, cytosine, or thymine. DNA takes the shape of a double helix with the bases on the inside pairing up via hydrogen bonds between adenine and thymine and cytosine and guanine. This structure was discovered in 1953 by Watson and Crick based on Rosalind Franklin's X-ray crystallography photos, though she was not recognized at the time. DNA encodes the instructions for life and has many applications today including cloning, genetic engineering, forensics, and medical diagnosis.

Nucleic acids DNA and RNA are made up of nucleotides which consist of a pentose sugar, phosphate group, and a nitrogenous base. Nucleotides bond together via phosphodiester linkages to form polynucleotides. DNA exists as a double helix with two anti-parallel polynucleotide strands bound via base pairing between adenine-thymine and guanine-cytosine. RNA differs in having ribose, uracil instead of thymine, and is typically single-stranded. Both DNA and RNA store and transmit genetic information in their sequence of bases.
Dna structure & central dogma
DNA contains the genetic instructions for making proteins and is found in all living organisms. It exists as a double helix structure with two strands bonded together via hydrogen bonds between complementary nucleotide bases. DNA stores and transmits genetic information from one generation of cells to the next through replication and protein production. It is studied for its central role in heredity and importance to life, as well as potential medical benefits like disease cures.
Dna
DNA is made up of nucleotides that contain genetic codes which determine a person's biological traits and ancestry. Mutations in DNA can change the proteins encoded by it or have no effect, depending on whether they alter the codons that specify amino acids. RNA plays a key role in protein synthesis by carrying the genetic message from DNA in the form of mRNA and directing the cell to assemble specific amino acid sequences according to the mRNA's nucleotide codons.
DNA structure and types
DNA is a double-stranded molecule that forms a helical structure. It is composed of nucleotides, each containing a phosphate group, deoxyribose sugar, and a nitrogenous base. There are two types of bases: purines (adenine and guanine) and pyrimidines (cytosine and thymine). The bases form rungs that link the strands via hydrogen bonds between adenine-thymine and guanine-cytosine. DNA exists in three primary structures - A-DNA, B-DNA, and Z-DNA - which differ in their helical geometry and handedness. The main role of DNA is long-term information storage in the genome that is used for building and maintaining
Proteins and nucleic acids notes
Proteins and nucleic acids are two important organic biomolecules. Proteins are composed of amino acids and perform functions like building body parts. Their building blocks are amino acids. Nucleic acids include DNA and RNA, store and pass on genetic information, and are composed of nucleotides consisting of a sugar, phosphate, and nitrogen base. DNA specifically contains adenine, thymine, cytosine and guanine and forms the classic double helix structure through base pairing between strands.
Dna presentation
DNA contains the genetic instructions that allow living things to develop, live and reproduce. It is made up of nucleotides with a sugar (deoxyribose), phosphate group, and one of four nitrogen bases (adenine, guanine, cytosine, thymine). DNA has a double helix structure, with the bases on each strand binding to their complement on the other strand. DNA replication is the process where the cell makes an identical copy of its DNA before cell division. It involves unwinding the DNA double helix, forming replication forks, and using each old strand as a template to build a new complementary strand. Replication can occur through conservative, semi-conservative, or dispersive mechanisms.
Chapter 4
This document discusses nucleic acids and their role in genetic information. Nucleic acids like DNA and RNA are made up of nucleotides and store and transmit genetic information. DNA exists as a double helix with complementary base pairing between adenine-thymine and cytosine-guanine. RNA is single stranded and less stable than DNA, suggesting it plays a role in expressing genetic information from DNA. The central dogma of molecular biology describes the flow of genetic information from DNA to RNA to proteins.

Huaorani – missionaries essay
American Christian missionaries made contact with the Huaorani people in Ecuador in the 1950s. Five missionaries were killed by Huaorani warriors. The author argues that the Huaorani warriors should not be punished for killing the missionaries for several reasons: a Huaorani lied about being attacked, the Huaorani did not speak English and did not understand the missionaries, and the missionaries had guns while the Huaorani only had spears. The author believes the missionaries invaded Huaorani territory and the Huaorani responded out of fear and confusion over the situation.

Lesson 13.3
Mutations are changes in genetic information that can be inherited. There are two main types: gene mutations which affect a single gene, and chromosomal mutations which involve changes to whole chromosomes. Gene mutations include point mutations like substitutions, insertions, and deletions. Chromosomal mutations involve changes in chromosome number or structure like deletions, duplications, inversions, and translocations. The effects of mutations vary - some have no effect, some are harmful by disrupting gene function, and some can be beneficial by producing variation that helps organisms adapt to changing environments.

Colonial history 2
European countries colonized the Americas in the 1500s due to overpopulation and lack of natural resources at home. Colonists from countries like England, France, Portugal, and Spain took land and resources in the Americas but largely killed, enslaved, or displaced the native populations. The colonization of the Americas by Europeans was one of the bloodiest and most horrific periods in human history for the genocide and slavery it inflicted upon millions of Native Americans and Africans brought as slaves.
Julian gomez
In Europe in the 1500s, overpopulation and poverty drove colonization of the Americas, where European colonists acquired new lands and opportunities but largely at the expense of Native Americans, millions of whom were killed, enslaved, forcibly intermarried or removed from their homelands. European colonists also imported African slaves to work in the Americas, especially after Native Americans proved more susceptible to death from slavery. The colonization had devastating impacts on indigenous populations through violence, enslavement and displacement from their lands.
Julian gomez
Colonization involves one group taking control of another's land, often through oppression, enslavement, and killing of indigenous peoples. Historically, Europeans and Americans were large colonizers in this way, but other countries also engaged in colonialism, such as China over Tibet, Indonesia over West Papua, and Russia's attempted colonization of Afghanistan. The colonized typically adopt the language and religion of their colonizers, and globalization has further spread Western culture worldwide at the cost of losing many traditional societies.

The chapter covers Griffith's experiments which showed bacterial transformation, Avery's work identifying DNA as the transforming factor, the Hershey-Chase experiment, Watson and Crick's DNA model, and differences between prokaryotic and eukaryotic DNA replication.
Contemporary Traditional Asmat Culture Part 2
According to Asmat tradition, Fumeripits was the first being on earth who created the first ceremonial men's house called a jeu. Fumeripits grew tired of being alone, so he carved human figures from trees and placed them in the jeu, but they remained inanimate. To bring them to life, Fumeripits created a drum from hollowed trees with stretched lizard skin and, as he played it, the figures came to life, unstuck their elbows from their knees, and began to dance, creating the first people as Asmat.
DNA Extraction Lab
This document provides the steps for a lab to extract DNA from strawberry cells. The objective is to understand how DNA is contained within cells and extract it. Materials needed include tubes, bags, filters, ethanol and other reagents. The method involves mashing strawberries to break open cells, filtering out solids, adding ethanol to precipitate DNA strands, then collecting and weighing the extracted DNA. Analysis questions address differences between prokaryotic and eukaryotic cells, cell membrane structure, and DNA structure and function.
Contemporary tradition asmat culture, part 1
The Asmat are an indigenous hunter-gatherer people living in West Papua, Indonesia, who are one of the last remaining hunter-gatherer cultures in the world. They have traditions such as piercing the nose septum and painting faces and bodies for ceremonies and war, but their culture is threatened by deforestation, colonization and assimilation that is ending their traditional way of life and replacing it with modern culture.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

AI & Electronic WarfareDandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Week1warmup
- 1. Week 1 Warm Up Explain the following characteristics of DNA. What is a double helix molecule? -is a double-stranded molecule that is twisted into a helix like a spiral staircase. Each strand is comprised of a sugar-phosphate backbone and numerous base chemicals attached in pairs. Why are hydrogen bonds important in DNA? -they are weak bonds - easier to break so DNA replication is easier whereas if they were covalent bonds DNA replication would not be possible What does it mean when we say that DNA has complementary bases? -the standard arrangement of bases in nucleotides in relation to their opposite pairing , such as thymine being paired with adenine and cytosine paired with guanine.
