Document Summary

Dna replication requiredfor the replicating organism in vivo = in a living cell or organism. Dna replication in cells the e. coli genome. Rate of replication is ~ 1000 base pairs per second. To replicate the entire e. coli genome (dna) replication = a little over an hour (base pairs!) Human genome = 3. 9 billion base pairs in. In reality though, dna replication (of the entire genome) in humans, takes ~ 1h few hours at a rate of 50 -75 bp/sec. C. available: the dna is too big. Replication start at origins of replication(with initiation of. A bacterial chromosome has a singleorigin of replication (oric) A eukaryotic chromosome has multipleorigins of replication (ori) (ori) Each progeny cell will contain: 1 parental strand (original, 1 newly synthesized strand of dna. Ligase: continuous strand, discontinuous strand, dna polymerase iii, dna polymerase i, helicase, okazaki fragments, primase, replication bubble, single stranded binding proteins (ssbp, sliding clamp, template dna, topoisomerase primase helicase.
