Question

17) Among the following statements which one best describes the “semi-conservative replication” of DNA?
A. The original parental DNA strands are present in all the replication cycles
B. In each replication cycle, only one of the two DNA strands is replicated
C. In each replication cycle, one of the two parental strands is conserved
D. In each replication cycle, only half of DNA is replicated

Answer 1

Answer:

          B. In each replication cycle, only one of the two DNA strands is replicated

Explanation:

        Semi-conservative replication. In this model, the two strands of DNA unwind from each other, and each acts as a template for the synthesis of a new, complementary strand. This results in two DNA molecules with one original strand and one new strand.
