Extraction of DNA from Cheek Cells Gene Smith February 29th 2013 INTRODUCTION DNA‚ deoxyribonucleic acid‚ is the genetic material of every living organism and is found in the nucleus of eukaryotic cells. DNA is often called the ‘blueprint for life’ because it contains the necessary information to carry out all the living processes of the cell (1).The purpose of this lab was to extract DNA from human cheek cells. The isolated DNA could be used inmapping or sequencing‚ PCR‚ crime scene investigation

DNA Extraction Lab Purpose: To compare the amount of DNA extracted from two different species‚ despite using the same method. Hypothesis: I predict that the liver will produce a higher quantity of DNA than the strawberry. This is because I believe that animals have a higher DNA yield because our structure is more complex than a plant’s structure. Materials: -Sample of Strawberries -Zip lock bag -DNA extraction buffer -Cold ethanol -Glass rod -Double ply cheese cloth -Two test tubes

Literature Review and Project Proposal AS6P01 Title: DNA Profiling Techniques in Forensic Science Abstract Since 1985‚ DNA profiling in forensic science has become very important in this virtual era of technology and in the world of science that solves both major and minor crimes. Small traces of DNA are considered in all circumstances from how the DNA was collected to fully obtaining the profile in its significant form. Traces of sweat‚ blood and semen are the most common type’s evidence

Module 2 Section 2 EXPERIMENT: DNA & Protein Synthesis Exercise 1 – Modeling DNA 1. List the four bases which are found in DNA. (1 pt) The four bases found in DNA are cytosine‚ adenine‚ guanine and thymine. 2. Fit any six nucleotides together to form a row‚ then list the six nucleotides in the order you used them. Work with your model pieces and try fitting the bases together to make a double strand as shown in Figure 9 of the lab manual. Which nucleotides form

increasingly complex task that requires active‚ continuing maintenance of digital media. This challenge has focused some interest on DNA as an attractive target for information storage because of its capacity for high-density information encoding‚ longevity under easily achieved conditions and proven track record as an information bearer. 1.2 Problem Statement: Previous DNA-based information storage approaches have encoded only trivial amounts of

Conclusion 3.2.1 1 Describe how the DNA code is translated into messenger RNA. DNA is translated into messenger RNA through transcription and translation. DNA is split through transcription and then it is translated to match into RNA. 2 How is the RNA molecule a “script” for the protein production process? RNA is a script for the protein production process because they set the RNA up to translate into a protein. 3 What is the function of hemoglobin in the body? Hemoglobin functions in the body by

DNA cloning: the basics Page: 307 Difficulty: 1 Ans: C Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the

Given the information that we now know about eyewitness testimony verses DNA science on page 440‚ this makes you stop and wonder about how many people have been wrongly imprisoned or put to death before DNA testing came along. From reading the article o page 440‚ it looks like the psychologists are using research to identify by showing individual pictures opposed to a police lineup; a person is most likely to choose an individual that may look close to the person that committed the crime.

Transformation of Bacterial Cells with Plasmid DNA Introduction: Transformation refers to the process in which the cell integrates foreign DNA to its genetic code‚ meaning it takes the genes and incorporates them into the cell’s current DNA. Cells that can do this naturally‚ most commonly bacteria and archea‚ are known as competent. The bacteria E. coli do not have high transformation competence under normal conditions‚ but can be manipulated to produce better results using

this‚ forensic scientists are forced to "bring out the big guns." Researchers can compare DNA samples from bodies to those taken directly from the victim: from hair‚ a toothbrush‚ a family member‚ and etcetera (Whitfield 6). As a result of the terrorist attacks‚ forensic scientists have come up with innovative tests and ways to interpret the resulting identification data (Whitfield 1). According to forensic DNA expert John Butler (National Institute of Standards and Technology in the city of Gathersburg
