Document Summary
The catastrophe killed 481 kemp"s ridley sea turtles, 600,000-800,000 coastal sea birds, 171 cetaceans. These differences can be resolved under electrophoresis: amplified fragment length polymorphism (aflp) analysis, short tandem repeats (str) analysis, match a sample from a crime site with a suspect. 4 base pairs: adenine, guanine, cytosine, thymine. Base pairs help form the ladder region of the tightly coiled double helix structure. Full genome is present in the nucleus of every living cell. Human genome (3 billion base pairs) unraveled would be about 6 feet long. Sequence analysis can yield info about species, population, and individual identification. How dna is used in forensics: species identification, sex identification, population assignment, parental analysis, individual identification. Str: short tandem repeats (unique to each individual) Collection of dna from a scene: muscle tissue samples are best for dna analysis, dna degrades over time. Rapid decay of kidney, spleen, liver, brain, and stomach. Clean gloves and new scalpel with each sample.
