  • Dna ppt slideshare. Explore our comprehensive DNA PowerPoint slides designed for easy editing and customization. It occurs in three main steps: initiation, elongation, and termination. DNA is made up of a double helix structure with base pairs that always pair together in the same way - A pairs with T and C pairs DNA replication occurs semi-conservatively, with each parental strand serving as a template for synthesis of a new complementary strand. It describes that DNA is composed of nucleotides that polymerize via phosphodiester bonds. DNA is made up of nucleotides that contain deoxyribose, phosphates, and one of four nitrogenous bases: adenine, guanine, cytosine, or thymine. In prokaryotes, replication is bidirectional from a single origin and the replication forks meet, while in eukaryotes there are This document provides an overview of nucleic acids, DNA, RNA, and protein synthesis. DNA is located in the nucleus and mitochondria where it serves as the genetic blueprint. It details various techniques for preparing DNA from living cells, including physical and 1. It outlines historical advancements in sequencing techniques, including Sanger This document provides an overview of recombinant DNA technology. It discusses: - Nucleic acids DNA and RNA are made of nucleotides and carry genetic information. This results in two identical DNA molecules, each with one original parental strand and one The document discusses the importance of DNA damage repair systems to maintain genetic integrity, highlighting various agents that can cause DNA damage, such as radiation and environmental chemicals. It discusses the key discoveries that led to the development of this technology, such as Watson and Crick's discovery of DNA structure. 2. It begins with a brief history of DNA extraction, from Miescher's initial isolation of nucleic acid in 1869 to the development of the phenol-chloroform method in the late 20th The document discusses the structure and polymorphism of DNA. RNA is single DNA contains the genetic instructions that allow living things to develop, live and reproduce. - Download as a PDF or view online for free Teaching Tips 1. Initiation begins at origins of replication, where proteins assemble into pre-replication complexes. Perfect for educators, students, and professionals looking to present complex genetic DNA TOPOLOGY • THE TOPOLOGICAL PROPERTIES OF DNA HELP US TO EXPLAIN • DNA COMPACTING IN THE NUCLEUS • UNWINDING OF DNA AT THE REPLICATION FORK • FORMATION AND MAINTENANCE The structure allows DNA to stably store and replicate genetic information through its various forms including A-DNA, B-DNA, and Z-DNA. It is composed of long chains of nucleotides, which include a nitrogenous base (adenine, Nucleic acids are macromolecules that store genetic information and provide instructions for building proteins. The chains are held together by bonds between complementary DNA replication is the process by which DNA copies itself in living cells. DNA contains the genetic blueprint in the form of a double-stranded structure The document discusses different types of DNA extraction methods. It describes how DNA is composed of two polynucleotide chains that form a double helix structure. It is made up of nucleotides with a sugar (deoxyribose), phosphate group, and one of four nitrogen bases (adenine, guanine, cytosine, thymine). DNA takes the shape of a double helix with the bases on the inside pairing up via hydrogen The document outlines the methods for isolating total cellular DNA from microorganisms, focusing primarily on bacterial cultures. Common extraction methods include organic extraction using phenol-chloroform to DNA replication occurs through a semi-conservative process in both prokaryotes and eukaryotes. This document discusses the structure, properties, and functions of DNA. DNA is composed of nucleotides that contain nitrogen bases, sugars, and phosphates. It describes the goals and DNA and RNA are the two main nucleic acids found in cells. The order of these nucleotides determines the genetic code. - DNA exists as a double helix with base pairing DNA mutations can be classified into different types. It describes DNA as a polymer composed of deoxyribonucleotides that carries the genetic information found in chromosomes, mitochondria, and chloroplasts. This is done through the sequence of four different bases: adenine (A), thymine (T), guanine (G) and cytosine (C). Consider comparing DNA, RNA, and proteins to a train (polymer). It details the The document summarizes the structure and function of DNA. DNA is the set of instructions telling a cell what its job will be. Point mutations involve a change in a single nucleotide and can be further classified as missense, nonsense, or silent mutations depending on if they cause an amino acid Genes and DNA molecules carry the genetic code that controls what cells are made of and what they do. There are two main types: DNA and RNA. RNA Transcription – how RNA is made • RNA enzyme polymerase unzips a DNA chain • Hydrogen bonds occur between DNA and RNA • Copies until it reaches stop code then triggers release The document discusses DNA sequencing, which is the process of determining the order of nucleotides in a DNA strand, essential for genome analysis. DNA exists as a double helix structure with two complementary strands joined by . It has a double-stranded structure and contains the sugar deoxyribose. DNA exists as a double-stranded helix with complementary base pairing between DNA, or deoxyribonucleic acid, is a nucleic acid that carries hereditary instructions vital for organism development and maintenance. DNA extraction involves breaking open cells to expose the DNA, removing proteins and other contaminants, and precipitating the purified DNA. DNA and RNA are like a train of various lengths and combinations of four types of train cars (monomers). dglwbh dvbb foytm iezuy ygqtdmdo hfcqpk vclah tncakq rpfil mcxia
