In gel electrophoresis‚ DNA fragments move through a porous matrix made of agarose‚ a gelatin-like substance purified from seaweed. The agarose is melted like Jell-O® and then poured into a plastic tray to harden into a slab called a gel. A plastic comb inserted at one end while the gel is hardening forms wells where DNA samples can be placed. The DNA is mixed with a loading buffer that contains glycerol—this makes it heavier than water‚ so it will sink to the bottom of the well. The gel is then

Partner: Rob Einersen Biology Period D Mr. Alvarez 15 February 2013 Gel Electrophoresis Introduction: Agarose Gel Electrophoresis is a process in which the process of determining whether a strand of DNA is either positively or negatively charged. The container in which the gel is stored has a negative and positive side; whichever side the DNA molecules go to means the DNA is charged the opposite way. (Ware‚ Lunte‚ Gardiner)For example if a DNA molecule goes to the negative

OUTLINE What is PCR and Gel Electrophoresis? • Polymerase chain reaction (PCR) is a technique which is used to amplify the number of copies of a specific region of DNA‚ in order to produce enough DNA to be adequately tested. This technique can be used to identify with a very high-probability‚ disease-causing viruses and/or bacteria‚ a deceased person‚ or a criminal suspect. • Gel electrophoresis is a widely used technique for separating electrically charged molecules. It is a central technique

known as DNA. In other words‚ it is the functional unit of heredity and acts as instruction to make molecules in later process which is protein that dictates cell function. Every person has two copies of each gene - inherited from each parent and they are located on chromosomes. The genes cannot be used unless they

The explosion of molecular biology techniques that began in the mid-1970s (and continues today) has provided tools to examine the physical structure of DNA‚ its nucleotide sequence and how genes are read and regulated. One key tool is the ability to visualize DNA molecules and determine their length by using a technique called gel electrophoresis. Introduction to gel electrophoresis In gel electrophoresis‚ DNA fragments move through a porous matrix made of agarose‚ a gelatin-like substance

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
