Bioinformatics Leigh Ann Santana DNA Extraction Lab DNA extraction is an important process because the DNA first needs to be purified away from proteins and other cellular contaminants. Cell are needed‚ because that is where the DNA is located. Inside almost every cell in our bodies is a nucleus‚ and inside each nucleus is about two meters of DNA. The following steps are needed to purify DNA from a cheek swab. Collect cheek cells‚ Burst cells open to release DNA‚ separate DNA from proteins and debris

will finish off talking about PCR‚ and then we will discuss how it can be used. If we go back to the slide of the double stranded DNA‚ and if we take that to a high temperature‚ the two strands separate‚ you then add the primers‚ which interact with ? On the strand‚ synthesis takes place in the 5-3 direction‚ then you end up with 2 molecules identical to the DNA‚ and then you do another round‚ so it’s an exponential increase. There are different enzymes and polymerases‚ which come from bacteria

MARKET CONCEPT TEST QUESTIONNAIRE Good morning/afternoon/evening. We are Joseph Caguimbal‚ Alexandra Florentino‚ Takehiro Morelos and Sarah Sosa‚ 3rd marketing students of the University of Santo Tomas. We are conducting a survey to determine the marketability of a proposed new product which is the Gardenia Bread Sticks. The product will be explained and deliberated more in the course of this paper. We would like to thank you for giving us the opportunity to ask for a few minutes of your

A DNA strand contains a complete representation of everything about our physiology. It also contains instructions on how to form our body by repeated divisions of a single cell. Each cell needs to know when it should‚ split into two‚ split into different kinds of cell for tissue differentiation. Cells also need to know when to stop growing because the body or organ is mature‚ and when it needs to replace tissue lost by injury. All of that is encoded into one molecule. So in other words the benefit

DNA FINGERPRINTING Background Reading - Nelson Biology and Campbell Biology Purpose - To understand the basics of DNA fingerprinting used in the Canadian courts for crime convictions and paternity suits. Introduction The process of DNA fingerprinting was developed by Professor Alec Jeffreys at Leicester University in 1984 as a form of genetic analysis. It was first used in the law courts of England in 1987 to convict a man in a rape case. It has now been used successfully in many crime and paternity

DNA is the single most important molecule found within cells. It is a stable polynucleotide‚ which contains coded information for inherited characteristics. It is contained in chromosomes in the nucleus of an eukaryot cell. The essential features of the Watson-Crick model are summarised below. 1. The two helical polynucleotide chains are coiled around a common axis. The two chains have opposite polarity i.e. they are antiparrallel. 2. The regular repeating sugar phosphate backbone of each strand

DNA Cloning PCB3063L Section DNA cloning refers to the process of making multiple copies of a DNA fragment. For the past weeks we have conducted a set of experiments that allow us to clone a specific gene in drosophila. First we started by the process of DNA extraction‚ which allowed us to isolate the genomic DNA from D. Melanogaster. This process requires the use of lysis in other to extract the DNA and RNA. After extracting the DNA‚ we it is important to use

This lab must be typed. Title DNA Fingerprinting Purpose Why are we doing this lab Background 1. What are restriction enzymes 2. When added to a DNA sample‚ what do restriction enzymes do 3. What do you call the specific sequence of bases the enzyme is searching for 4. What is a restriction digestion 5. What is the purpose of the water bath 6. The electrophoresis apparatus creates an electrical field with positive and negative poles at the ends of the gel. DNA molecules are negatively charged.

DNA REPLICATION At the replication origin DNA helicase attaches to a strand of DNA and begins to break apart hydrogen bonds in order to unravel a section of the double helix. The section of DNA that is unwound is called the replication bubble and the “Y” shaped sections are called the replication forks. In order to stop the unwound section from binding back together‚ single strand binding proteins react with the single strand portions on the DNA causing them to stay separated. Although the leading
