this experiment is to investigate the process of Electrophoresis and successfully analyse DNA fragments. Hypothesis: That the experiment will show the visual representation of DNA proteins‚ and that the shorter the band the further is will travel. Background: Restriction enzymes are DNA-cutting enzymes found in bacteria‚ which cut DNA into smaller fragments. A restriction enzyme recognizes and cuts DNA only at a particular sequence of nucleotides‚ known as restriction sites. Restriction enzymes

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

Introduction A mutator strain is one that lacks certain repair methods when a mistake is made during DNA replication. The strain of E. coli that was used in this lab‚ XL-1 Red Mutator‚ lacked three different repair methods used to correct mistake in DNA replication. If a mistake occurred‚ the E. coli would not be able to make repairs via DNA polymerase backtracking‚ mismatch repair‚ or oxo-dGTP hydrolysis. The E. coli will still be able to use the other ways to repair mistakes including SOS

Chromosome is in the nucleus of every cell. Each chromosome is mostly made up of coiled DNA. Besides DNA‚ there are also proteins in each Chromosome. The interesting point is that in Chromosome‚ DNA tightly coiled a lot of times around proteins and it supports the basic structure of chromosome. The way that Chromosome forms motivates me to think of how DNA and proteins in the Chromosome relate to each other both in the aspect of location and the aspect of biology function. For the second question

Determining Allele Frequencies of the PV92 Alu Element using DNA Isolated from Human Cheek Cells and PCR Amplification Background Alu elements are the most abundant repetitive elements in the human genome that have mobilized throughout primate genomes by retrotransposition over the past 65 million years ago from a 5’ to 3’ fusion of the 7SL RNA gene‚ to reach the present number of more than one million copies. Over the last few years‚ several lines of evidence demonstrated that these elements

The Precogs’ Dehumanization In Minority Report and "The Minority Report” How we define human‚ subhuman and superhuman is complex‚ with many intricacies and unknowns. The relationship between them‚ regarding the Precogs in The Minority Report short story as well as the film‚ is complex between these two forms of dehumanization and humanization. For those unfamiliar with the works‚ the three Precogs are collectively‚ literally‚ the human engine which enables Precrime to exist. In both works‚

DNA databases: crime fighting weapon or threat to privacy 1- A DNA database is a database that contains a profile of bodily fluid left by criminals at the crime scenes. It has developed by the biology laboratory of the Florida department of law enforcement. These profiles are sent to nationwide DNA bank. There are several benefits of these DNA databases. First‚ the DNA can be used as evidence in trials. It allows criminals to be identified by their own genes. Second‚ the computer analysis

morphological features by using DNA barcoding technique is an important application for molecular biology and genetics. In this study‚ we used special fish called bonito fish. These fishes generally live in relatively warm and hot seas and grow until they reach a length of about 30 inches. Bonito fish have a long pectoral fin and two dorsal fins. Also‚ they have a forked tail. Animal species and their origins can be detected accurately and quickly with the help of the technique called DNA barcoding (Hanner et

important technique used in the field of molecular science. The field of forensics utilizes agarose gel electrophoresis by allowing investigators to determine from a sample of DNA removed from a crime who the suspect may be. Investigators of a crime can run the DNA collected through gel electrophoresis and then compare this DNA to suspects involved. Large amounts of knowledge can be gained about various aspects of proteins and nucleic acids by researchers implementing a few
