BOTANY 130 Study Guide - Final Guide: Okazaki Fragments, Dna Polymerase, Start Codon
Document Summary
Replication transcription rna translation protein. Watson and crick made model of dna: a women, r. franklin was never recognized for her contribution, m. wilkins became friends with watson & crick. 4 different nucleotides: a & g = purines, c & t = pyrimidines. Double helix nucleosomes fiber of packed nucleosomes . Different organisms have different sizes of genome: in multicellular organisms, every somatic cell has two sets of genome, in the gametic cells, each cell has one genome. G2 = cell grows and prepares for division (chromosomes condense) Replication bubble forms: helicase unwinds the helix, binding proteins hold bubble open, topoisomerase deals with super coiling. Replication: rna primer is attached by rna primase attaches to dna, dna polymerase travels from the 5" 3" direction. Lagging strand: same as above but fragments are created, dna polymerase replaces where the primer was, dna ligase connects the okazaki fragments. Transcirption occurs in the nuclues, mitochondria, and chloroplast.
