DNA‚ as we all know‚ is esteemed with the title of ‘Master Molecule ’. The three letters of DNA denotes of deoxyribonucleic acid .Now the thing that we ponder on is why DNA is so important to us. Why are the researchers & scientist persistently working on DNA? Why it is so important to know the tiniest details of DNA structure and function.?The simplest answer for “Why Is DNA Important?” is that DNA is the prerequisite for life’s inception. Firstly‚ it transfers hereditary information from

Introduction to genetics. For other uses‚ see DNA (disambiguation). The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structure of two base pairs are shown in the bottom right. The structure of part of a DNA double helix Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates

DNA Analysis The importance of DNA analysis has made an impact the forensic world by proving the innocence or guilt of a person. DNA analysis is the most effective method in the Forensic Investigation field‚ it carries more evidentiary value than other forensic evidence‚ it has become a primary source for cases that have not been solved and the advancements in technology will continue to scientifically eliminate wrongful convictions. Although many feel that there are discrepancies in DNA analysis

area of DNA‚ deoxyribonucleic acid‚ helping on scientific research and most importantly as a tool for solving crimes. Before the usage of DNA‚ people only had shreds of evidence on the crime which could be detected by the naked eye. However‚ with the development of DNA detection technology‚ the police can identify or get some indication about the malefactor by collecting pieces of evidence that were impotent before; for example‚ hair‚ fingerprints and even blood (Travis‚ 1998). However‚ DNA testing

DNA Research Paper DNA Structure: DNA (deoxyribonucleic acid) is the code for life; it makes up the genetic material of living organisms. DNA is a long molecule made up of many subunits‚ or monomers‚ called nucleotides. Nucleotides are made up of three parts: a sugar‚ a phosphate group‚ and a nitrogenous base. Nucleotides contain a sugar-phosphate backbone and bases. There are four bases in DNA: adenine‚ cytosine‚ guanine‚ and thymine. A (adenine) always pairs with T (thymine)‚ and C (cytosine)

Extracting DNA from Bananas In the Lab: Extracting DNA from Bananas‚ DNA was removed from bananas that had been blended with water in order to examine how DNA is seen from the naked eye. DNA stands for deoxyribonucleic acid‚ which is a nucleic acid that contains the sugar deoxyribose. DNA is made up of a series of monomers called nucleotides. Each nucleotide has three parts: a deoxyribose molecule‚ a phosphate group‚ and a nitrogenous base. In addition‚ there are four kinds of nitrogenous

- DNA TESTING - "It’s good to know where you come from. It makes you what you are today. It’s DNA‚ it’s in your blood. Alexander McQueen".DNA testing is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organism‚ with the exception of some viruses can solve many mysteries and I believe there are three main reason why it is beneficial for society. First‚ DNA can solve criminal cases.it could help police to investigate crimes

Introduction:Dna evidence has been known for many years in crime scenes.Dna evidence was first discovered in 1986.Dna evidence can find anyone by finding blood‚skin cells‚hair‚saliva‚and semen.Dna evidence can be good at finding people 95% at a time‚because of the cells in the dna. Problems:The problem with dna evidence is there’s ways to avoid it.Ways you can avoid it is by wearing a mask‚gloves‚and clean things you touched.The reason you need to do that is because there are things that will help

determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments of DNA from another source

the structure of DNA they wanted to use the information to help them identify how DNA is replicated. Three different theories of replication were proposed by Watson and Crick. The semi-conservative model‚ where the DNA strand splits into two halves‚ which will then create a new DNA strand consisting of the old original half and a new half. The conservative model where the whole of the original DNA strand acts as a template and is replicated to make a completely new strand of DNA. The dispersive model
