What did BTK stand for? DNA: Deoxyribonucleic acid contains the genetic instructions that control the biological development of our cells and the proteins the cells make. Though all humans share 99.9% of their genes, our DNA differs from everyone else's by three million nucleotide base pairs. how many are different? Which allele you have at a particular site is determined by your parents' genetic data and meiosis, as well as any errors in replication. This is what makes DNA profiling so certain. Choose up to three primers and click Run analysis. business math. They're called CODIS sites, which stands for the FBI's Combined DNA Index System. Ballistics. Create more primers using other parts of the chromosome. A. They might use their knowledge of CAD (computer-aided drawing) to create a reconstruction of the crime scene. "If there's new technology and we are able to potentially solve something, we want to keep working at it, because ultimately we're trying to do it for the family," he said. The random chance that all 13 CODIS sites match is (1/10)13 = one in 10,000,000,000,000.
