The principal enzyme involved in DNA replication is called

15

True or False: Replication in most prokaryotic cells starts from a single point and procees in 2 directions until the entire chromosome is copied

16

True or False: In eukaryotic cells, replication may begin at dozens or even hundreds of places on the DNA molecule, proceeding in both directions until each chromosome is completely copied.

17

RNA is similar to DNA in that it is a nucleic acid that consists of a long chain of
