BIOL 1510 Lecture Notes - Lecture 4: Bacterial Conjugation, Plasmid, Eukaryote
Document Summary
27 notes: prokaryotes- very evolvable able to replicate dna in hot water can live in glaciers can live in salt crystals can live in space. Why are bacteria so good at evolving? (we have been evolving the same time as bacteria) Ex: people living in warm environments hard,skin color, body shape, sweat glands, / humans have to think of more like our brain, q-10 ratios, Short generation time- rate of reproduction (the change of evolution happens at a generational level not individuals) very simple- less linked traits. C. high variation- huge population number will generate a lot of variation. A. clonal reproduction- having an ideal optimize type share dna horizontally- transfer adaptive traits horizontally. A. bacteria can package up that gene and send it to another bacteria. ex: having bacteria in you, one strand can build resistance; is evolvability (selects from what already there) Ex: observbing power an speed of evolution: bacteria features:
