The term semiconservative refers specifically to which aspect of DNA replication?
A
DNA replication occurs only in one direction along the template strand.
B
Each new DNA molecule consists of one parental strand and one newly synthesized strand.
C
Both strands of the original DNA molecule remain together after replication.
D
Each new DNA molecule is composed entirely of newly synthesized strands.

Understand the term 'semiconservative' in the context of DNA replication. It describes how the original DNA molecule is copied during replication.
Recall that DNA replication involves separating the two strands of the original DNA molecule, each serving as a template for a new complementary strand.
Recognize that 'semiconservative' means each new DNA molecule retains one of the original (parental) strands paired with one newly synthesized strand.
Contrast this with other possible models of replication, such as conservative (where the original molecule remains intact and a completely new molecule is made) or dispersive (where strands are mixed segments of old and new DNA).
Conclude that the semiconservative model specifically refers to the fact that each daughter DNA molecule consists of one parental strand and one newly synthesized strand.
