DNA and RNA are nucleic acids that store and transmit genetic information. DNA is a double-stranded helix that stores genetic information in the nucleus. RNA is a single-stranded helix that transmits genetic information and helps synthesize proteins. Both are composed of nucleotides with phosphates and sugars, though DNA contains deoxyribose and RNA contains ribose. They differ in their nitrogenous bases as well, with DNA containing thymine and RNA containing uracil instead. DNA replication is the process where a double-stranded DNA molecule makes two identical copies of itself, going through steps of replication fork formation, primer binding, elongation, and termination.

DNA
DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all living organisms. It is composed of nucleotides containing phosphate, sugar, and one of four types of nucleobases. The nucleotides bond together to form two strands that coil around each other in the shape of a double helix. DNA stores the genetic code in sequences of nucleobases along its backbone and is located in the nuclei of eukaryotic cells or in the cytoplasm of prokaryotes, where it directs protein synthesis and cell division. James Watson and Francis Crick were the scientists who discovered the structure of DNA in 1950.
CELL REPLICATION.pptx
Protein synthesis involves transcription and translation. During transcription, DNA is copied into messenger RNA (mRNA) in the nucleus. The mRNA carries the genetic code from DNA to the cytoplasm for translation. Translation is the process by which the mRNA genetic code is used to produce a specific amino acid sequence or protein with the help of transfer RNA (tRNA) and ribosomes. The central dogma of molecular biology states that genetic information flows from DNA to RNA to protein.
Dnapresentation
The document discusses the structure and functions of DNA and genes. It explains that DNA is composed of nucleotides containing phosphate, deoxyribose sugar and one of four nitrogenous bases. The bases on one strand bond with those on the other through hydrogen bonds to form the DNA double helix. Genes are sections of DNA that code for specific functions and traits. The document outlines the different types of genomes found in organisms, including prokaryotic, eukaryotic nuclear, viral, organellar and plasmid genomes. It also describes the processes of DNA replication and transcription of DNA into RNA, which plays a role in protein synthesis.
Unit 2 Notes
The document describes the structure and function of DNA and RNA. It discusses how DNA is made up of nucleotides containing deoxyribose, phosphate groups and nitrogenous bases. DNA forms a double helix structure with base pairing between adenine and thymine and cytosine and guanine. RNA is similar in structure but contains ribose and uracil instead of thymine. The document outlines how DNA is replicated semi-conservatively and how genes are transcribed into mRNA and then translated into proteins with the help of tRNA and ribosomes.
Nucleic Acid
Nuclei acid is a naturally occurring chemical compound containing phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines).
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. DNA is the chemical basis of heredity and may be regarded as the reserve bank of genetic formation. DNA is exclusively responsible for maintaining the identity of different species of organisms over millions of years.
RNA is the genetic material of certain viruses, but it is also found in all living cells. The genes control protein synthesis through the mediation of RNA.

DNA is a long, double-stranded molecule composed of nucleotides that functions to store genetic information. It consists of two polynucleotide chains coiled around each other to form a double helix structure. The two chains are held together by complementary base pairing between adenine (A) and thymine (T), and between guanine (G) and cytosine (C). This complementary base pairing involves hydrogen bonding between the nitrogenous bases and forms the rungs of the DNA ladder.

Dna and rna
DNA contains the genetic instructions used in the development and functioning of all known living organisms. It is a nucleic acid located in the cell nucleus that contains the sugar deoxyribose. DNA replicates itself with high accuracy before cell division due to the specific base pairing of adenine with thymine and cytosine with guanine. RNA plays an important role in protein synthesis by carrying instructions from DNA in the nucleus to the cytoplasm. There are three main types of RNA: messenger RNA, ribosomal RNA, and transfer RNA.
Nucleic Acids
Nucleic acids are made up of nucleotides, which consist of a sugar (ribose in RNA and deoxyribose in DNA), phosphate group, and a nitrogen base. DNA stores genetic information in its double-helix structure formed by base pairing of adenine-thymine and guanine-cytosine. RNA has uracil instead of thymine and is usually single-stranded. DNA remains in the nucleus, while RNA carries DNA's protein instructions out to the cytoplasm for protein synthesis.
Dna synthesis and protein synthesis
Nucleic acids are macromolecules that store genetic information and provide instructions for building proteins. There are two main types: DNA and RNA. DNA contains the genetic blueprint in the form of a double-stranded structure located in the cell's nucleus. RNA is single-stranded and involved in protein synthesis. The central dogma of molecular biology describes how DNA is transcribed into RNA then translated into proteins. DNA replication is the process where DNA makes a copy of itself during cell division which involves unwinding of the DNA double helix, addition of nucleotides to form new strands, and production of two identical DNA molecules.

Nucleic acids : they are biopolymers, or substantial biomolecules, fundamental to every single
known type of life. They are made out of monomers, which are nucleotides made of three
segments: a 5-carbon sugar, a phosphate assemble, and a nitrogenous base. In the event that the
sugar is a straightforward ribose, the polymer is RNA (ribonucleic corrosive); if the sugar is
gotten from ribose as deoxyribose, the polymer is DNA (deoxyribonucleic corrosive).
Nucleic acids are seemingly the most critical of all biomolecules. They are found in plenitude in
every living thing, where they capacity to make and encode and after that store data in the core
of each living cell of each life-shape living being on Earth. Thusly, they capacity to transmit and
express that data inside and outside the cell core—to the inside operations of the cell and at last

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.

DNA Replication in Prokaryotes and Eukaryotes .pptx
DNA replication is the process where a cell makes an exact copy of its DNA before cell division. It occurs during the S phase of the cell cycle and involves unwinding the DNA double helix, making RNA primers, and synthesizing new DNA strands in both directions from the origin of replication using the old strands as templates. This results in two identical copies of the DNA. The key enzymes involved are DNA helicase, DNA polymerase, DNA ligase, topoisomerase, and single-stranded binding proteins. Replication proceeds through the semi-conservative model and results in the production of leading and lagging strands made of long and short Okazaki fragments respectively.

WAVES, SOUND, AND LIGHTtttttttttttttt.pptx
Waves transfer energy through matter and space without transferring matter. There are two main types of waves: mechanical waves which require a medium and electromagnetic waves which can travel through empty space. Sound waves are longitudinal mechanical waves that transfer energy through collisions of particles in a medium. Light waves are electromagnetic waves of varying frequencies and wavelengths that make up the electromagnetic spectrum.

The document discusses the history of models of the universe from ancient geocentric to modern heliocentric models. It describes that the Big Bang occurred 13.7 billion years ago from a singularity. Ancient Greeks like Thales, Anaximander, and Pythagoras proposed early geocentric models with the Earth at the center. The Ptolemaic geocentric model incorporated spheres and was most developed by Claudius Ptolemy. Later, heliocentric models placed the Sun at the center, proposed by thinkers like Aristarchus of Samos, Copernicus, Galileo, and laws of planetary motion were developed by Kepler.

The nail consists of the nail body, nail root, and free edge. Structures beneath the nail include the nail bed, matrix and lunula. Structures surrounding the nail include the cuticle, eponychium, hyponychium, perionychium, nail walls and nail grooves. The health and condition of nails can reflect overall health and be influenced by factors like nutrition.
DESCRIPTORS OF MOTION.pptx
- Mechanics is the study of motion and the forces acting on objects. It is divided into kinematics, which deals with describing motion without regard to forces, and dynamics, which deals with how forces affect an object's motion.
- Distance refers to the total length traveled by an object, while displacement includes both distance and direction of travel from a starting point.
- Speed is how fast an object moves over time, while velocity includes both speed and direction of motion. Acceleration is the rate of change of velocity over time.
- Graphs can be used to plot position over time to represent different types of motion like constant speed, changing speed, etc.

Seismic waves (1).pptx
Seismic waves are energy that travels through and on the surface of the Earth, causing shaking and vibrations during earthquakes. There are two main types of seismic waves: surface waves, which travel along the Earth's surface, and body waves, which travel through the Earth's interior. Surface waves include Rayleigh waves, which cause rolling motions, and Love waves, which cause side-to-side motions and can damage structures. Body waves consist of faster P-waves and slower S-waves; P-waves push and pull materials while S-waves generate shear motions. Scientists study body waves to learn about the Earth's internal structure and composition.
Meteoroids-Group-7-presentation-redone.pptx
Meteorites are interplanetary bodies that range in size from fractions of a millimeter to hundreds of meters. When they enter Earth's atmosphere, they are called meteors or shooting stars and heat up due to friction, with smaller ones vaporizing and bigger ones potentially striking the surface. Meteorites can be classified based on their composition as iron-nickel types, stony types made of silicates and metals, or stony-iron mixtures.
Endocrine System.pdf
The document summarizes the key components and functions of the endocrine system. It defines the endocrine system as composed of glands that secrete hormones like oxytocin, growth hormones, insulin, and estrogen. These hormones are chemical messengers released into the bloodstream that regulate functions in our bodies, like metabolism, growth, and reproduction. The major glands discussed include the pituitary gland, thyroid gland, adrenal glands, pancreas, testes/ovaries, thymus, and pineal gland. Disorders that can result from issues with the endocrine system like obesity, osteoporosis, goiter, gigantism, and dwarfism are also briefly mentioned.
NERVOUSSYSTEM (1).pptx
The document summarizes key aspects of the nervous system. It describes how the nervous system is divided into two major parts: the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is further divided into the brain and spinal cord. The brain contains the cerebrum, cerebellum, and brain stem. The PNS connects the CNS to organs and limbs and has two divisions - the somatic nervous system and autonomic nervous system. The somatic system controls voluntary body movement while the autonomic system regulates involuntary functions like breathing and heart rate.

SERIES AND PARALLEL.pptx
A series circuit has components connected one after the other so that there is only one path for current to flow through all components. A parallel circuit has multiple paths for current to flow through components. The major difference is that in a series circuit the same current flows through each component, while in a parallel circuit the current splits and divides between components.
RNA.pptx
The three nitrogenous bases in mRNA form codons to code for amino acids, which are the building blocks of proteins. The Central Dogma explains the process of DNA being transcribed into mRNA and then translated into protein. Ribosomes are the sites in cells where protein synthesis occurs through the joining of amino acids specified by mRNA.
nerve-cell.pptx
The document discusses the nervous system and its basic unit, the neuron. It describes the key parts of a neuron including the dendrites, cell body, and axon. Dendrites carry signals toward the cell body, while the axon carries signals away from the cell body. A nerve impulse travels along the axon and uses neurotransmitters to cross the synapse between neurons to stimulate the next neuron. The nervous system relies on five sense organs to receive information from the environment and send it to the brain to help the body respond to stimuli and ensure survival.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
