DNA molecules are found in the cytoplasm of prokaryotes and nearly all DNA is located in the nucleus of eukaryotes. DNA polymerase is the main enzyme that links individual nucleotides into DNA molecules during replication as shown in the diagram.
Warmup week2
This document is a warm up quiz on basic biology concepts. It contains 4 multiple choice questions that assess knowledge of where DNA is located in different cell types, the main enzyme involved in linking nucleotides to form DNA, and identifies the process shown in a diagram as DNA replication.
Nucleic acids 1
The document discusses the history and structure of nucleic acids. It describes how Friedrich Miescher first isolated nuclein in 1869 and how the tetranucleotide hypothesis proposed nucleic acids contained one of each nucleotide connected by phosphodiester linkages. Later, Avery, MacLeod and McCarty showed DNA could transform cells, supporting it as the molecule of heredity. Watson and Crick finally determined DNA's double helix structure in 1953. There are two main types of nucleic acids, DNA and RNA, which have similar structures but RNA contains uracil instead of thymine and has a 2' hydroxyl group.
Molecular basis of inheritance
This document provides information on DNA structure and replication. It describes that DNA is made of two polynucleotide chains held together by hydrogen bonds between complementary nucleotide bases. Replication of DNA is semiconservative, meaning each new DNA molecule contains one original and one newly synthesized strand. Experiments by Meselson and Stahl using isotopes of nitrogen demonstrated that replication results in daughter DNA molecules with one original and one new strand, supporting the semiconservative model proposed by Watson and Crick.
Molecular basis of inheritance
Nucleic acids are macromolecules found in all living cells that contain genetic information. There are two main types of nucleic acids: DNA and RNA. In 1953, Watson and Crick proposed their famous double helix model for the structure of DNA based on X-ray crystallography data. Their model showed that DNA consists of two strands coiled around each other, with nucleotides on each strand pairing with each other through hydrogen bonds. Adenine pairs with thymine and guanine pairs with cytosine. This discovery established that DNA is the genetic material.
Molecular basis of inheritance
DNA replication is semi-conservative, with each new DNA molecule containing one old and one new strand. Several enzymes are involved, including DNA polymerase, helicase, and ligase. The leading strand is replicated continuously while the lagging strand involves discontinuous replication of Okazaki fragments that are later joined. Primers of RNA are required to initiate synthesis, with DNA polymerase then adding complementary nucleotides to the 3' end to extend the DNA chain. Chargaff's rules and the double helix model of DNA provided evidence that DNA is the genetic material.
Dna structure and analysis
DNA caries genetic information of organisms. This presentation covers the discovery of DNA as genetic material, structure of DNA, Nucleotides and nucleosides. Watson and crick DNA model.
The molecular basis of inheritance
1. The document discusses the discovery of DNA as the genetic material through experiments in the early 20th century. Key evidence came from studies showing that DNA from one bacteria could transform another harmless strain into a pathogenic one.
2. Further evidence came from studies of viruses that infect bacteria, which showed that only the DNA component of the viruses was able to enter bacterial cells and provide genetic information.
3. The structure of DNA was determined in 1953 by Watson and Crick through building physical models. They proposed the double helix structure with nucleotides on two spiraling backbones linked by hydrogen bonds between complementary nucleotide pairs.

Transformation
The document provides information about bacterial transformation. It describes that transformation is the process by which bacteria take up extracellular DNA from their environment. Frederick Griffith first discovered transformation in 1928 while working with pneumococcus bacteria. His experiments showed that a non-virulent rough form could be transformed into a virulent smooth form by DNA from a heat-killed smooth strain. Later experiments by Avery, Macleod and McCarty demonstrated that DNA is the transforming principle and genetic material of bacteria. The document then discusses various methods of bacterial transformation including chemical and physical methods like electroporation and use of calcium chloride. It also explains the molecular mechanism of transformation involving DNA binding, penetration, synapsis formation and integration into the bacterial chromosome.

DNA
Frederick Griffith's experiment in 1928 showed that something from dead virulent bacteria could transform live non-virulent bacteria of the same species, allowing them to become virulent. Later experiments by Avery, MacLeod and McCarty in 1944 identified that the transforming principle was DNA. Further evidence that DNA carries genetic information came from Hershey and Chase's 1953 experiment with bacteriophage virus infecting E. coli bacteria, which showed that viral DNA, not proteins, entered the bacterial cells.
Watson and crick model of dna
Watson and Crick proposed a model of DNA structure in 1953 as a double helix with two antiparallel strands coiled around the same axis. Each strand consists of alternating deoxyribose and phosphate groups with purine or pyrimidine bases stacked inside. Adenine always pairs with thymine via two hydrogen bonds and guanine pairs with cytosine via three hydrogen bonds. Their model explained experimental X-ray diffraction data and Chargaff's rules of base equivalence. The discovery revolutionized our understanding of genetics and heredity.
Nucleic acid and its chemistry, dna as genetic material
The nucleic acids are vital biopolymers found in all living organisms, where they function to encode, transfer, and express genes. The nucleic acids are of two types, namely deoxyribonucleic acid (DNA) and ribonucleic acid(RNA).
EVER WONDERED WHY DNA IS GENETIC MATERIAL INSTEAD OF RNA OR PROTEIN?
Gene to protein paragraph
The document summarizes a workshop that taught how proteins are formed in the body from DNA. DNA contains genetic codes that determine the structure and function of proteins and other cellular components. During the workshop, students extracted DNA from cheek cells and used techniques like PCR and electrophoresis to replicate and separate DNA, demonstrating how specific genes and proteins are identified. These techniques have various applications in forensics, research, genetic engineering, and paleontology.
Polymerase Chain Reaction
Polymerase chain reaction (PCR) is a technique used to amplify a specific region of DNA through repeated cycles of heating and cooling. It requires a DNA template, primers, DNA polymerase, nucleotides, and magnesium chloride. The process involves denaturation of the DNA strands, annealing of primers to the complementary sequences, and extension of the primers by DNA polymerase to synthesize new strands. PCR can be used to amplify small amounts of DNA for forensic analysis or isolate a known gene from a genome. However, it is limited to amplifying up to 5kb of known DNA sequences.

16 the molecular basis of inheritance
This document provides an overview of the discovery of DNA as the genetic material. It discusses early evidence from experiments transforming bacteria and showing that viral DNA enters bacterial cells. It also describes Rosalind Franklin's X-ray crystallography work that provided insights into DNA's structure and allowed Watson and Crick to deduce the double helix model with paired nitrogenous bases. Their model resolved the structure and showed how DNA could store and replicate the genetic information required for inheritance.
Genetic Transformation Lab
The document summarizes a student laboratory experiment attempting to genetically transform E. coli bacterial cells with a GFP plasmid (pGLO) using heat shock. The expected results were that bacterial cells transformed with the plasmid would grow on ampicillin-containing media and glow under black light. However, the actual results found that all bacterial cells died on ampicillin-containing plates, contradicting expectations. Possible sources of error that could have caused transformation failure are discussed.
DNA TO PROTEIN
DNA is the genetic material that is copied through the process of replication to produce two identical DNA molecules. During replication, the two strands of the DNA double helix separate and each strand acts as a template for the production of a new complementary strand. This results in two DNA molecules that are identical to the original. DNA contains the sugar deoxyribose and the nitrogenous bases adenine, guanine, cytosine, and thymine. The order of bases in DNA contains the genetic instructions that are used to direct the synthesis of proteins.
Colonizationnotes
Colonization of other people and countries occurred for exploitative reasons like capturing slaves, stealing land and resources to gain wealth. The Spanish colonized much of the Americas to do this, and today Latin Americans descend from both European and native American heritage. Globalization originated from colonization as colonized peoples adopted the colonizers' language and religion, and now as the world globalizes more, traditional cultures may disappear as places grow more American and European.
Periodfourpresentation.
This document summarizes evidence that supports the theory of evolution from four perspectives: biogeography, the age of the Earth and fossils, comparative anatomy and embryology, and genetics and molecular biology. Each section provides examples for how scientific observations in these areas help trace evolutionary relationships and document how species have changed over time from common ancestors through natural processes like natural selection. The document also discusses how recent research on Galapagos finches supported Darwin's original hypotheses about natural selection by showing adaptations to seasonal changes.

Asmat culture part_1
The Asmat are an indigenous hunter-gatherer culture living in West Papua, Indonesia, on an island north of Australia in the South Pacific Ocean. They are one of the last remaining hunter-gatherer cultures in the world, with traditions including nose piercing and painting faces and bodies for ceremonies and war. However, deforestation, colonization, and assimilation are negatively impacting traditional Asmat culture, potentially bringing an end to one of Earth's last hunter-gatherer societies as the modern world influences their way of life.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
