BIOL 282 Lecture Notes - Lecture 8: Lactose Intolerance, Petri Dish, Auxotrophy
Document Summary
Slide 5: the white spot is the empty cell & all the lines around it is chromosomal. Dna: there"s separate circular dna that are plasmids & are separate from the normal chromosomal dna. Slide 11 mutants: don"t need to memorize what these stand for but you do need to understand the basic concept. Slide 19: conjugative plasmid that gets transferred through the process of, no chromosome transfers, only plasmid. Slide 20: with the conjugation bridge, the f- cell will gain the transferred f+ plasmid. & will become f: the original f+ cell synthesized it"s f+ plasmid before transferring it & remains as f+ even after transferring. Slide 22: how do chromosomes get together, recombination requires cell to cell contact. Slide 23: fertility plasmid can recombine with/into the chromosome, a site that is homologous to the cite on the chromosome, (only 1000 base pairs long, site-specific recombination.
