What enzymes are involved in DNA replication? - ANSWER-DNA dependent DNA polymerase is DNA replication anabolic or catabolic - ANSWER-anabolic what were the 3 competing models of DNA replication - ANSWER-- semiconservative - conservative - dispersive semiconservative DNA replication - ANSWER-each daughter DNA molecule is composed of one original strand and one new strand conservative DNA replication - ANSWER-- the parent strands separate and act as templates - then the original parent...

Who performed classic experiments that supported the semiconservative model of DNA replication? - Meselson and Stahl What separates the DNA strands during replication? - helicase A new DNA strand elongates only in the 5' to 3' direction because - DNA polymerase can only add nucleotides to the free 3' end. What is the role of DNA ligase in the elongation of the lagging strand during DNA replication? - It joins Okazaki fragments together
