This document discusses the structure and formation of DNA. It explains that DNA is made up of nucleotides connected through phosphodiester bonds. When nucleotides want to attach to form DNA, they must be in the form of triphosphates which contain energy. This energy is released during bonding between the nucleotides, creating strong phosphodiester bonds that hold the DNA chain together. Enzymes like nucleases can break these bonds, while DNAases and RNAases break down DNA and RNA, respectively.

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.
Atp
ATP is an organic compound that contains adenine, ribose sugar, and three phosphate groups. It serves as the primary energy source within cells and is necessary for functions like muscle contraction, moving substances across membranes, and generating nerve impulses. ATP supports life by providing energy for cellular processes, transporting substances, and powering muscle movement.

The document summarizes the structure of DNA. It describes that:
1) James Watson and Francis Crick described DNA as a double helix structure.
2) A DNA nucleotide contains a deoxyribose sugar, phosphate group, and a nitrogen base (adenine, cytosine, thymine, or guanine).
3) In DNA, adenine pairs with thymine and guanine pairs with cytosine to form the rungs of the DNA ladder structure.
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.
DNA part 2
This document discusses the building blocks of DNA. It explains that nitrogenous bases attach to sugars to form nucleosides, and that nucleosides become nucleotides when a phosphate group attaches to the nucleoside. Specifically, it provides the examples of adenosine, guanosine, cytosine, and thymidine becoming nucleotides. The document also notes that adding more phosphate groups to a nucleotide, such as one, two, or three phosphates, produces adenosine monophosphate, diphosphate, and triphosphate respectively, with the latter being an energy-rich compound known as ATP.

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.

Photosynthesis Overview
Photosynthesis uses energy from sunlight, captured by the pigment chlorophyll in chloroplasts, to convert carbon dioxide and water into oxygen and energy-rich sugars. Electrons produced during light absorption are transferred by electron carrier molecules like NADPH to drive the chemical reactions that ultimately fix carbon into sugars. The overall equation for photosynthesis is: carbon dioxide + water + light energy → sugars + oxygen.
DNA structure
In the 1950s, James Watson and Francis Crick used molecular modeling to discover that DNA has a double helix structure, with each strand made of linked nucleotides containing a phosphate group, sugar, and nitrogenous base. DNA replication occurs as one strand serves as a template for the other new strand, with adenine always pairing with thymine and guanine always pairing with cytosine between the two strands to maintain the uniform structure.

The double helix consists of the sugar-phosphate backbones on the outside and complementary bases forming hydrogen bonds on the inside in the well-known A-T, C-G pairing.
Structure Of Dna
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
The document summarizes the structure and function of DNA. It describes DNA as being made up of nucleotides that form two strands twisted into a double helix ladder shape. The nucleotides consist of a sugar, phosphate, and one of four nitrogen bases that bond together the strands in specific base pairings of A-T and C-G. DNA stores genetic information through the sequence of these base pairs and can make copies of itself through a process called replication where the strands separate and new complementary strands are assembled.
Cellular Respiration
The document describes the process of cellular respiration which occurs in three main stages: glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis converts one glucose molecule into two pyruvic acid molecules while producing ATP and NADH. The Krebs cycle further breaks down pyruvic acid to extract more energy in the form of ATP, NADH, and FADH2. Finally, the electron transport chain uses the electrons from NADH and FADH2 to power ATP synthesis, producing about 36 molecules of ATP per glucose molecule through the entire cellular respiration process.

This document discusses the structure, properties, and functions of DNA. It describes DNA as a polymer composed of deoxyribonucleotides that carries the genetic information found in chromosomes, mitochondria, and chloroplasts. The basic structure of DNA involves two anti-parallel strands coiled around each other to form the familiar double helix structure, held together by hydrogen bonds between complementary nucleotide base pairs and base stacking interactions. DNA exists in various structural forms and undergoes compaction in the cell, ultimately forming chromatin through association with histone proteins. The primary function of DNA is to serve as the template for its own replication and transcription into RNA to direct protein synthesis.

DNA replication in prokaryotes occurs rapidly, completing replication of the E. coli genome in 42 minutes. Replication initiates at a single origin of replication and proceeds bidirectionally around the circular chromosome. DNA polymerase III is the main enzyme that synthesizes new DNA strands. The leading strand is synthesized continuously while the lagging strand is synthesized discontinuously in short Okazaki fragments. Replication terminates when the two replication forks meet on the opposite side of the origin of replication at termination sites.

DNA replication in bacteria occurs through a semiconservative process whereby the parental double-stranded DNA separates and each strand serves as a template for synthesis of a new complementary strand. Meselson and Stahl's experiment provided evidence that replication occurs through this semiconservative model. DNA replication involves multiple enzymes that work together at the replication fork, including DNA polymerase III, helicase, primase, ligase, and topoisomerases. Replication initiates at the origin of replication and proceeds bidirectionally until termination is complete.
DNA STRUCTURE, REPLICATION AND MANIPULATION
DNA is a polymer made up of nucleotides. Each nucleotide contains a nitrogenous base, a 5-carbon sugar called deoxyribose, and a phosphate group. There are four nucleotides differing by their bases: adenine (A), guanine (G), cytosine (C), and thymine (T). DNA replication copies DNA through semiconservative replication using DNA polymerase. DNA polymerase adds nucleotides to a growing strand using the existing strand as a template. Lagging strand synthesis occurs discontinuously in short segments called Okazaki fragments. PCR amplifies specific DNA regions using repeated heating and cooling cycles and DNA polymerase to exponentially produce millions of copies of the target DNA.

DNA Replication
The process by which DNA molecule makes its identical copies is known as DNA replication or DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule
DNA replication .pptx
DNA replication is the process by which DNA copies itself in order to pass genetic information to daughter cells. It occurs through a semi-conservative process whereby the double helix unwinds and each strand acts as a template for new partner strands. DNA polymerase adds nucleotides to extend the new strands from primers in the 5' to 3' direction. On the leading strand synthesis is continuous but on the lagging strand it occurs discontinuously in fragments called Okazaki fragments that are later joined by DNA ligase. Telomerase adds repetitive sequences to the ends of lagging strands during replication to compensate for nucleotide losses and prevent shortening of chromosomes.
Topic 3: Nucleic Acid
The document discusses several key aspects of DNA structure and replication:
1. The Hershey-Chase experiment provided definitive evidence that DNA, not protein, carries the genetic material of organisms. They found that labeled viral DNA entered infected bacteria cells, while labeled viral proteins did not.
2. Rosalind Franklin's X-ray crystallography of DNA provided data that helped Watson and Crick discover the double helix structure of DNA. DNA is made of nucleotides with a phosphate group, sugar, and nitrogenous base.
3. DNA replication is semi-conservative and relies on complementary base pairing between DNA strands. It involves enzymes that unwind, separate, and replicate both DNA strands.
Dna relication in eukaryotes
Eukaryotic DNA replication is a conserved mechanism that restricts DNA replication to once per cell cycle. Eukaryotic DNA replication of chromosomal DNA is central for the duplication of a cell and is necessary for the maintenance of the eukaryotic genome.
DNA replication in eukaryotes occurs in three stages: initiation, elongation, and termination, which are aided by several enzymes. Because eukaryotic genomes are quite
complex, DNA replication is a very complicated process that involves several enzymes and other proteins. It occurs in three main stages: initiation, elongation, and termination.
DNA replication.pptx
DNA replication in prokaryotes occurs through three main steps: initiation, elongation, and termination. Initiation begins at the origin of replication when DnaA and other proteins help separate the DNA strands. Elongation then uses DNA polymerases and other enzymes to bidirectionally copy the DNA in a semiconservative manner, producing both a leading and lagging strand. Termination occurs when the replication forks meet at the terminus region, utilizing proteins like Tus to stop replication.
DNA Grade 12
Chromatin, which contains DNA and proteins, is found in the nucleus of eukaryotic cells. Histone proteins help package DNA into chromatin and condense it further into chromosomes during cell division. DNA is a double-stranded polymer composed of nucleotides containing a sugar, phosphate, and one of four nitrogenous bases. It forms the twisted ladder-shaped structure known as a double helix and carries the genetic instructions that are passed from parents to offspring. DNA replication is the process where DNA copies itself before cell division, involving unwinding of the DNA strands, formation of a replication fork, and synthesis of new strands along the original templates.
Nucleic acids 2
The document discusses nucleic acids and their role in genetics. It begins by defining nucleic acids as important biopolymers that contain genetic information and facilitate its transfer between generations. It then describes the two main types of nucleic acids: DNA and RNA. DNA contains the full genetic code and resides in the nucleus, while RNA carries messages from DNA and has various functions. The document proceeds to discuss the composition, structure, and functions of nucleic acids in more detail.

DNA Structure PowerPoint
1. DNA is made up of deoxyribose, phosphate groups, and four nitrogenous bases (adenine, guanine, cytosine, thymine).
2. The bases pair up through hydrogen bonding between complementary base pairs (adenine with thymine, cytosine with guanine).
3. The paired bases and sugar-phosphate backbone form the structure of the DNA double helix, with the bases in the middle and the backbones on the outside.
Nucleic acid..pptx
1. Nucleic acids are polymers of nucleotides that store genetic information. There are two types: DNA and RNA. (1 sentence)
2. DNA is found in the nucleus and contains the genes, while RNA is involved in protein synthesis and can be found in various cellular locations. The structures of DNA and RNA are similar but DNA contains thymine while RNA contains uracil. (1 sentence)
3. DNA replicates semi-conservatively to produce two identical DNA molecules during cell division. RNA is synthesized from a DNA template in a process called transcription. There are three main types of RNA: mRNA, tRNA, and rRNA, which have different roles in protein synthesis. (1 sentence)
Aamir khan gold
Aamir Khan presented to Dr. Muhammad Ateeq Qurashi on DNA and RNA on July 24th, 2018. The presentation discussed the history and discovery of nucleic acids including DNA and RNA. It explained the structures of DNA and RNA, including that DNA is a double-stranded helix composed of nucleotides with base pairing between adenine and thymine or cytosine and guanine. RNA also contains nucleotides but with uracil instead of thymine and a ribose sugar instead of deoxyribose in DNA.
L7. Nucleic Acids.ppt
This document discusses nucleic acids such as DNA and RNA. It notes that nucleic acids were discovered by Friedrich Miescher in 1869 and are essential for life. DNA controls chemical changes in cells and determines cell and organism type. DNA is made up of nucleotides containing a sugar, phosphate group, and organic base. The nucleotides are linked by phosphodiester bonds to form long chains coiled into the famous double helix structure. The central dogma explains how DNA information is transcribed into RNA and then translated into proteins.
DNA REPLICATION IN PROKARYOTES.pptx
DNA replication uses a semi-conservative method that results in two double-stranded DNA molecules, each with one old parental strand and one new daughter strand. Replication occurs through the theta and rolling circle mechanisms in prokaryotes. The theta mechanism involves unwinding DNA at the origin of replication and creating replication forks that allow bidirectional synthesis of new strands. The rolling circle mechanism involves nicking one strand at the origin, allowing it to be replicated unidirectionally as it "rolls" off the parental strand.

7.1 dna & replication
The document discusses the structure and replication of DNA. It explains that DNA has a double helix structure that allows it to efficiently store and replicate genetic information. DNA replication is carried out by a complex system of enzymes and involves unwinding the DNA double helix, synthesizing new strands to complement the existing strands, and joining fragments on the lagging strand. While most of the DNA codes for proteins, some regions have important regulatory functions or code for other molecules like tRNAs.

Cross cylinder af soomaali
This document describes how to use a cross cylinder to determine if a patient needs cylindrical lenses and to refine the axis and power of any needed cylindrical correction.
A cross cylinder consists of two opposite cylinders. It is used to identify if a patient requires cylindrical lenses, and if so, to refine the axis and power. To check if a patient needs cylindrical lenses, the cross cylinder is aligned at 90 degrees to the patient's spherical lenses and flipped between +0.25 and -0.25. If the patient notices no difference, they do not require cylindrical lenses. If they prefer one orientation, they are astigmatic and need cylindrical lenses.
To refine the axis, the cross cylinder is aligned with the axis of

DNA part 3
- 1. DNA part 3 Prep by :Mohamed Abdukadir Kalif Mphil in optometry
- 2. As we told on our previous lectures a nucleotide looks like the one in the picture , and many such nucleotides put together will make DNA
- 3. • Every nucleotide has two ends , one end is carbon position number 5 in which now there is phosphate attached , and the other end is carbon position number 3
- 4. • In DNA the nucleotide it contains are connected in such a way , that the carbon position number 3 end of Adenine is connected with carbon position number 5 of Guanine , and u can see in the upcoming picture
- 6. So what happens When nucleotides wants to attach with one another to make DNA
- 7. When in the cell DNA synthesis is going on , the nucleotide which are present with in the cell should be triphosphate , because the triphosphate are rich of energy they will be accepted in other nucleotides in order to make a chain of DNA
- 8. When a nucleotide of a triphosphate comes to attach with another nucleotide , energy should be released in order to create a strong bond between the two nucleotides , to make a chain of DNA
- 9. In DNA formation the nucleotides are held together by strong bonds which are created by the release of energy , these bonds are called phosphodiester bond
- 11. The enzyme which can break down the phosphodiester bond is called Nucleases
- 12. • And the enzyme which can break down the DNA is called DNAases • And the enzyme which can break down the RNA is called RNAases
- 13. • To be continued
