5. Which of the following statements describes processes that occur during DNA replication?
A. A DNA sequence is read by RNA polymerase, which produces another
RNA strand complementary to the first strand.
B. Two free-floating single strands of DNA are joined by polymerase. The
polymerase finds the point at which the two strands will match up into a
double strand.
C. Messenger RNA are decoded by a ribosome to produce an amino
acid chain. In the cell's cytoplasm, transfer RNA joins the messenger RNA,
forming a polypeptide.
D. A double-stranded DNA molecule is unwound into single strands.
Polymerase matches the right nucleotides to the single strand so that
each forms a double strand of DNA.
