BIOL 3300 Lecture Notes - Heteroduplex, Kin Selection, Quantitative Genetics
Document Summary
Uniparental: organellar dna (no repair mechanisms) Some sex chromosomes: ex: y chromosomes. Problems with size homoplasy: (ac20) (ac18, (ac16) (ac18, these two above are now the same size. Greater association results in more pairs sharing food. More pairs will share if they are related by 0. 5: think of who you are more willing to share with between a cousin or a sibling. Re-anneals at different rates dependent on copy number: highly repetitive dna. Homoduplex homo = same, duplex = 2. Heteroduplex hetero = difference, duplex = 2. The more hydrogen bonds there are, the more heat is required to make the dna single stranded. (seen in the graph using emu dna) In humans we get it from our mothers. Usually bigger in plants compared to animals. Mutation rate is much slower in plants compared to animals. Steps: denaturation (heat the dna, annealing (the primers, elongation. Het it up and denature it till you have 4 copies.
