strategies for testing are also discussed. THE BASICS Isolation of DNA and Polymerase Chain Reaction (PCR) DNA or RNA for genetic testing is almost always isolated from peripheral-blood leukocytes. This requires that the blood be drawn in tubes containing some sort of anticoagulant. The preferred anticoagulants are either citrate or EDTA. The cells are lysed followed by removal of the other cellular components and precipitation of the DNA or RNA in ethanol. One of the drawbacks of this approach is that

Evolution Big Idea Project Chris Berg There are many people that are not fully informed about the concept of evolution. Because of this, they are unable to make scientific and logical connections between us humans and how we evolved from the world around us. There are a broad number of misconceptions that people have, but I decided to focus on 3 major ones: 1. Evolution is goal oriented. Many non-evolutionists say that if evolution existed, there would be some endpoint or “goal” that is

that is coded for the production of tryptophan. DNA forms a protein. The tryptophan is an amino acid that is part of most proteins The tryptophan is also a repressor that attaches to the protein formed, making it become active. Transcription is then blocked when the active repressor is

simple idea—the instructions for making all this life are written in nucleic acids, usually DNA. Most organisms have a set of DNA that contains the instructions for making that creature. This DNA contains four “letters” in which these instructions are written—A, T, G, and C. The only difference between the code for a dog and the code for a geranium is in the order of those letters in the code. If you took the DNA from a human and rearranged the letters in the right way, you could produce an oak tree—arrange

is DNA evidence from the criminal. Once the DNA evidence is collected they will attempt to create a DNA profile to match the assailant to one of the suspects. Although this procedure may seem perfect, when put into action, there are often several issues. One of the biggest issues is the fact that the DNA sample collected from the scene is incomplete. Often only partial samples are collected and it leaves room for doubt during the prosecution. In addition, during laboratory analysis of the DNA sample

You should already be familiar with many of these concepts from other courses. 1. It is believed that the first organisms appeared on Earth around 3.8 billion years ago. What evidence do each of the following for this occurrence? • Stromatolites -the earliest forms of lfe for which we have clear fossil evidence -a bulbous mass of sedimentary layers of limestone accreted by microbes over years -within the outer layers, microbes grow as a microbial mat (sort of like a biofilm) -outer laters

Genetic Enhancement on the Human Genome The debate on whether human genetic engineering should be researched and used as the main alternative solution to disease have been going on since the creation of the "human genetic engineering" phenomenon. The ethical question is clear: should money be invested in human genetic engineering and should we research it at all, even if it is formally criticized by all monotheistic religions? The ethical principles in conflict are beneficence (people with fatal
