(True or False) The process of DNA replication results in a copy of the original DNA molecule.   Terms. The signature form of mammalian mtDNA is the displacement-loop (D-loop) molecule, which maintains a short piece of nascent strand at the leading-strand origin of replication. • The fidelity of replication is improved by proofreading by a factor of ~100. On the following drawing, label the directions (5’ and 3’) on both strands. Get step-by-step explanations, verified by experts. DNA replication is a semi-conservative process because half of the parent DNA molecule is conserved in each of the two daughter DNA molecules.
