extraction and amplification of DNA (Mullis et. al. 1986). 2. PCR has the ability to isolate specific DNA sequences with the use of primers. This is done by denaturing the DNA (at 95o C) so it is able to anneal to the primers that specify a fragment to be amplified (Mullis et. at. 1986). These primes anneal to a specific sequence of DNA in order to amplify this desired sequence. Once the annealing process is complete‚ the primers are extended (at 30o C) by a DNA polymerase added to the reaction

2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are negatively charged‚ the gel is

what part of your DNA really comes from your mom? Or which part comes from your dad? The answers to these questions can easily be found out with DNA Fingerprinting. Created in 1984‚ DNA Fingerprinting has become a major importance to the world by helping find the criminal in a case‚ figuring out who the father is when unknown‚ and finding the identification of an unknown body. DNA Fingerprinting can be taken from simple things like a strand of hair or even a dried bloodstain. DNA is everywhere‚ and

BIO 219 Group 1 Section 66 October 19‚ 2012 The extraction of purified DNA from A. fischeri by restriction digestion using Sal I enzyme and pGEM for shotgun cloning Introduction: The ultimate goal of this experiment is to isolate the lux operon‚ a targeted piece of DNA that causes bioluminescence‚ from Aliivibrio fischeri and insert it into the DNA of Escherichia coli in order to make it glow. A. fischeri is a gram-negative bacteria which participates in a symbiotic relationship with

PLASMID DNA ISOLATION‚ RESTRICTION ENZUME DISGESTION AND AGAROSE GEL ELECTRIPHORESIS Abstract: The gel is covered with an ion- containing buffer‚ such as (TAE)‚ that controls the pH of the system and conducts electricity. overall DNA concentration was lower than expected. Using agarose gel electrophoresis is to separate and visualize the DNA fragment‚ which is produced by restriction enzymes . Introduction: The purpose of this experiment is to measure the size of the fragments of DNA and separate

the process of gel electrophoresis separate DNA fragments? It uses an electric current to separate different-sized molecules in a porous‚ sponge-like matrix. 2. What is the purpose of the agarose gel? It is used to separate DNA molecules that range in different lengths. 3. What is the purpose of adding blue “tracking” dye to the DNA samples? The blue tracking dye is added to help load the samples easily and helps able to see the DNA moving through the gel. 4. Explain why DNA has an overall

Restriction Fragment Length Polymorphism and Southern Blotting 1. Abstract The aim of the experiment was to be introduced to the techniques involved in the identification of restriction fragment length polymorphisms. Restrictions were carried out using three different restriction enzymes‚ ECORI‚ HindIII and BstELI with their buffers. Lambda (λ) DNA was then examined using electrophoresis and Southern blotting. The results showed that λ DNA was best digested by EcoRI as all of the expected bands
