Essential Cell Biology 4th Edition by Bruce Alberts – Test Bank 6-1 The process of DNA replication requires that each of the parental DNA strands be used as a to produce a duplicate of the opposing strand. (a) catalyst (b) competitor (c) template (d) copy 6-2 DNA replication is considered semiconservative because . (a) after many rounds of DNA replication, the original DNA double helix is still intact. (b) each daughter DNA molecule consists of two new strands copied from the parent DNA molecule. (c) each daughter DNA molecule consists of one strand from the parent DNA molecule and one new strand. (d) new DNA strands must be copied from a DNA template. 6-3 The classic experiments conducted by Meselson and Stahl demonstrated that DNA replication is accomplished by employing a mechanism. (a) continuous (b) semiconservative (c) dispersive (d) conservative 6-4 Initiator proteins bind to replication origins and disrupt hydrogen bonds between the two DNA strands being copied
