BIOL 142 Lecture Notes - Lecture 14: Pilus, Bacterial Conjugation, Mendelian Inheritance
Document Summary
Reconstruct the order of the gene map based on the recombination frequencies listed below. Built into meiosis process crossing over and independent assortment variation is important for evolution by natural selection. When they differ and environmental conditions change, it"s more likely some subset off that population will survive and pass on their alleles. When everyone"s a clone, leads to extinction: given bacteria can only reproduce asexually, do bacteria lack in genetic variation, yes. Need to understand to address this problem for humans. Conjugation: involves the transfer of dna from a donor cell to the recipient cell via a sex pilus. How genetic information can be moved from one cell to another. Transformation: involves the transfer of genetic information by means of. Used when wanting to see how a human/mouse/etc. protein will be expressed. Can recombine into main chromosome to change the phenotype. Competency is determined by having a specific receptor on the cell surface.
