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

DNA Extraction Lab Problem Statement: Do you think you have ever eaten DNA? Background Information: DNA is too small to see under a regular microscope‚ so how can it be studied? DNA is a large molecule found in all living things; therefore it is possible to extract it from cells or tissues. All we need to do is disrupt the cell’s plasma membrane and nuclear envelope‚ make the DNA clump together and - voila! - DNA extraction is possible. DNA extractions from onion‚ bananas‚ liver‚ or wheat

Shahadah Williams Case Report Introduction: At 4:30 pm‚ April 26‚ 2013 Detective Shi Henry called asking for assistance in processing a suicide victim‚ involving a 39-year-old female at the corner of Midland and Colvin Street. Victim name is Ariel Travis. Me (Shahadah Williams) and my Crime Scene Search Team Jim Carey and Will Ferrell arrived approximately 15 minutes after the phone call. I’m a forensic technician with 12 years of experience‚ and a bachelor degree in forensics. Upon arrival I spoke

DNA profiling is a method of identifying an individual by unique characteristics of their DNA. A specific DNA pattern‚ called a profile‚ is obtained from an individual or a sample of tissue. This allows the comparison of the base sequence of two or more DNA samples to determine whether they are related. DNA profiling has many uses‚ in prevention of economic fraud‚ dietetic work‚ and classifying species‚ identifying bodies‚ forensic science‚ screening for disease‚ and investigating paternity.

purpose of this lab experiment was to discover genetically modified organisms. We analyzed our results and found that our sample was GMO positive. These results were attained through polymerase chain reaction and agarose gel electrophoresis. We came to the conclusion that the presence of a band in lane 4 confirms that there are indeed genetically modified organisms. Introduction: Overall‚ the main purpose of this experiment was to conduct gel electrophoresis combined with PCR in order to determine

DNA Aim This practical procedure allows you to amplify a 460 basepair fragment of DNA from within the control region of the mitochondrial genome. This can be done using three water baths or‚ if one is available‚ a thermal cycler (PCR machine). After it has been amplified‚ the DNA is run on an electrophoresis gel. Note: This method has been adapted from one developed by the Dolan DNA Learning Center at Cold Spring Harbor Laboratory. More details are available from the DNA Learning Center’s

Purpose In this lab‚ we used PCR and gel electrophoresis to identify genetically modified food. Introduction A genetically modified organism is an organism whose DNA or genetic makeup has been modified to code for certain desirable traits("Genetically Modified Foods"). Common genetically modified plants include corn and soy‚ and common genetically modified animals are fish. Many genetically modified plants are coded to resist bugs‚ grow faster‚ and produce bigger fruit‚ while most GMO animals

expressed ldhA gene was inserted into pET28b plasmid vector. The resulting recombinant pET28b-LdhA expression vector was then transformed after introduction into E. coli. The ligation gave 15 colonies of recombinant DNA which later gave 6 recombinant plasmids as revealed by gel electrophoresis. 1.

Similarities between PCR and bacterial DNA replication Replication and transcription involves a parental DNA strand that is the foundation on which the products are built on. Replication and transcription both have initiation step which involve the breakage of the parental DNA strand. Replication and transcription both have specific proteins that keep the polymerase molecule attached to the parental DNA strand. There are elongation factors for transcription and sliding clamp for replication.
