BIOL-UA 12 Study Guide - Final Guide: Sodium Dodecyl Sulfate, Tris, Panmixia
Document Summary
Q: what does edta do? allows us to get to the dna. Chelates (binds) magnesium and calcium ions prevents enzymatic degradation of. Dna by nucleases, which require these ions to be active. Sodium dodecyl sulfate (also known as sodium lauryl sulfate) Found in many detergents, as well as shampoo and toothpaste. Ethanol, assisted by salt, causes the dna. To pellet the dna, so that we can get it out of the solution. The frequency of alleles and corresponding genotypes in a population of sexually reproducing diploid species reaches equilibrium after one generation of random mating and will remain constant if only the chromosomal segregation and recombination are at work. Useful when we want to determine whether natural selection or other factors are causing evolution at a particular locus (a null hypothesis for evolution) Many poisons are alkaloid (and thus bitter) P2 + 2pq + q2 = 1.
