BIO206H5 Study Guide - Final Guide: Dna Polymerase Iii Holoenzyme, Dna Polymerase Ii, Dna Replication
Document Summary
Bio206 tut0113: a) conservative: one of the three models of dna replication is the conservative model. In this model, dna replication involved the formation of two new daughter strands from the parent templates. The two new strands join together to create a new double-helical dna molecule. Dna molecule would conserve half of the original double-helical dna molecule: dispersive: in this model, the parental dna molecule is broken into fragments. Both strands of dna in each of the daughter molecules is made up of an assortment of fragmental parental and new dna: continuous: during dna replication, the elongation phase is characterized by two different strands. The leading strand (5" to 3" template strand) and the lagging strand (3" to 5" template). On the leading strand, dna polymerase iii can read the template and add nucleotides to the new strand continuously: discontinuous: the lagging strand is synthesize discontinuously in short fragments in the opposite direction to the replication fork.
