DNA replication is called semiconservative because __________.
A) each daughter DNA consists of one new helix and one old helix
B) each daughter DNA consists of one new nucleotide and one old nucleotide
C) each daughter DNA consists of one new chromatid and one old chromatid
D) each daughter cell receives one new chromatid and one old chromatid
E) each daughter cell receives one new helix and one old helix

Question

Quizplus · Accepted Answer

Semiconservative DNA replication means that each daughter DNA molecule consists of one original (old) strand and one newly synthesized strand. This is because during replication, each original strand of DNA serves as a template for the synthesis of a new complementary strand, resulting in two daughter DNA molecules that are identical to the original DNA molecule. Therefore, choice A, which states that each daughter DNA consists of one new helix and one old helix, is the correct answer.
