The Antiparallel Polarity of the Two DNA Strands Within the Double

question 16

Multiple Choice

The antiparallel polarity of the two DNA strands within the double helix affects DNA replication in that

• A)it takes twice as long to replicate two strands sequentially from 5′ to 3′.
• B)circular bacterial DNA does not have polarity, so a single strand can be copied twice.
• C)DNA polymerases synthesizing both strands move in the direction of the replication fork, one strand is replicated discontinuously.
• D)each portion of the double helix must be unwound twice so that both strands are replicated continuously.
