The strand which elongate towards replication fork is:
Correct answer: A. Leading strand
- A. Leading strand
- B. Lagging strand
- C. Both (A) and (B)
- D. None of the above
Explanation
Leading strand, which elongates toward the replication fork, is built up simply by adding nucleotides continuously to its growing 3' end. In contrast the lagging strand which elongates away from the replication fork, is synthesized discontinuously as a series of short segments that are later connected.
