In DNA replication, one new strand is synthesized complementary to an old (parent) strand and is referred as

  • A.mutational
  • B.semiconservative
  • C.discontinuous
  • D.antiparallel

Answer: B

Correct answer: semiconservative

Because each daughter duplex keeps one parental strand and gains one new one, half of each product is “conserved” from the parent - hence semi-conservative. Antiparallel describes the opposite orientation of the two strands, and discontinuous the way the lagging strand is made; neither is the name for this pattern of inheritance.
