DNA SPOOLING ISOLATION OF DNA FROM ONION INTRODUCTION This project will demonstrate several basic steps required for isolation of chromosomal DNA from cells. To extract the chromosomal DNA‚ both the cell membrane and the nuclear membrane must be broken open. This is accomplished by disrupting the membranes with a solution of detergent and salt‚creating a cell homogenate. Once the DNA is released from the nucleus‚ it must be protected from nucleases‚ enzymes which will degrade the DNA. Keeping

2 Production of Protein from Cloned Genes Now that we have covered the basic techniques involved in gene cloning and DNA analysis and examined how these techniques are used in research‚ we can move on to consider how recombinant DNA technology is being applied in biotechnology. This is not a new subject‚ although biotechnology has received far more attention during recent years than it ever has in the past. Biotechnology can be defined as the use of biological processes in industry and technology

Strawberry DNA Extraction Donovan Roberts Mrs. Caudill Honors Biology 3/7/11 Introduction The structure of DNA is made of nitrogenous bases‚ phosphate groups‚ and sugars. These three parts of DNA form hydrogen bonds and create a right-handed double helix. The location of DNA in a eukaryotic cell is found within the nucleus‚ bound to proteins. DNA can be extracted from within the cell. They are several steps you must take to retrieve DNA from within the cell. When extracting DNA cells can

Prof. Fincke PH250 December 13‚ 2012 Moral Psychology Introduction: People throughout history and diverse cultures have long debated over what deems our decisions‚ actions‚ and judgments right‚ wrong‚ good‚ or evil. Moral Psychology is a field that is at a crossroads within the fields of psychology and philosophy in the debate between good and bad. One of the ways Moral Psychology tries to define our moral judgments is through arguing that they are reasoned by our basic‚ human emotions. Paul

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA really stands for Deoxyribonucleic acid. DNA is a right handed double helix. Nucleotides that mount together by phosphodiester bonds make up DNA. It also contains a spiral strand that is made of phosphate backbone and secure bases (Adenine‚ Guanine‚ Cytosine‚ Thymine). Cytosine and Thymine are Pyrimidines‚ while Adenine and Guanine are Purines.

RNA uses uracil instead of the thymine in DNA. DNA replicates itself and RNA is synthesized from RNA on an as-needed basis. Their stability and reaction is also different. DNA is more stable and less reactive than RNA because of the deoxyribose sugar’s C-H bonds. It is stable in alkaline conditions; DNA has smaller grooves‚ which makes it harder for enzymes to “attack.” RNA is more reactive because of the ribose sugar’s C-OH‚ hydroxyl‚ bonds. Unlike DNA‚ it is not stable in alkaline conditions and

The purpose of module E is to learn several DNA techniques in the lab including DNA purification with solubility and absorption‚ plasmid transfection of E.coli‚ colony screening by PCR and quantitative PCR. First part of the experiment E1 show the purification method of DNA through solubility. E. coli lysate mixed organic solvents to purify the DNA present in solution. First‚ the lysate was mixed with phenol/chloroform‚ then vortexed‚ and centrifuged. We extracted the aqueous layer and combined
