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...
