At the completion of DNA replication in a eukaryotic cell, which of the following statements is correct?
A
The original DNA molecule remains unchanged and two new molecules are synthesized separately.
B
Each daughter DNA molecule consists of one parental strand and one newly synthesized strand.
C
Each daughter DNA molecule contains two parental strands.
D
Both daughter DNA molecules are composed entirely of newly synthesized strands.
Verified step by step guidance1
Recall the mechanism of DNA replication in eukaryotic cells, which is described as semiconservative replication.
Understand that in semiconservative replication, each of the two daughter DNA molecules contains one original (parental) strand and one newly synthesized strand.
Recognize that the original DNA molecule does not remain intact as a whole; instead, its strands separate and serve as templates for new strands.
Eliminate options that suggest both strands are either entirely parental or entirely new, as these contradict the semiconservative model.
Conclude that the correct statement is that each daughter DNA molecule consists of one parental strand and one newly synthesized strand.
