The Polymerase Chain Reaction and Determination of Alu Population Freqencies Porshia Gibbs April 8‚ 2010 Genetics Laboratory Abstract Cheek cells were extrapolated and used in PCR amplification and electrophoresis of the amplified samples to determine the presence or absence of the dimorphic Alu sequence in a class population. A bioinformatic allele server was then employed to calculate genotypic and allelic frequencies of the Alu element in the class population. The Hardy-Weinberg equation

Isolated DNA Products Amplified Via Polymerase Chain Reaction and Cloned Biotechnology: DNA WPUNJ December‚ 2012 Abstract Isolated DNA from mouse‚ plants‚ and plasmid DNA were used for Polymerase Chain Reaction (PCR) for DNA amplification. The purpose of this experiment was to study the success rate or optimization of PCR of DNA‚ using both manual and kit methods. This set of experiments gives an insight to the relative difficulties associated with the optimization of a variety

Wanni Lin Biology 110 March 2‚ 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

order to analyze a dna molecule in a molecular biology lab you must determine the length in nucleotide pairs. Electrophoresis is an extremely useful tool in order to compare the mobility on agarose gels with dna markers of known lengths. Dna is a polymer that is negatively charged due to the sugar phosphates. When dna is on an electric field such as the electrophoresis gel the different lengths of dna migrate at different rates when they move through the porous gel. The ends of the gel are marked with

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 (Mullis et. al

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation‚ scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites‚ ensuring that all DNA fragments that contain a particular sequence have the

Enzymes and Electrophoresis Bhumik Patel Phillips 1/16/11 Restriction enzymes are tools in DNA research that can cut DNA into exactly needed pieces. Certain cuts can be rough‚ while others can be clean. Certain cuts can have an organized pattern to have a staggered cut. Other cuts will leave complementary bases with them. Electrophoresis allows the manipulation of DNA to separate and organize those parts. Electrophoresis is the substrate electric movement of the separation of DNA. Gel Electrophoresis

The team of forensic anthropologists ran a gel electrophoresis with DNA from Skeleton 3 and two missing persons‚ Julia Ly and Teresa Chen to help in DNA identification. This process would allow restriction enzymes to cut by a specific restriction site and run through the gel‚ where the DNA fragments would move from the negative side to the positive side of the gel due to the negative charge of the phosphate group in DNA. The smaller the DNA fragments‚ the further they move down the gel. As mentioned
