Multiple Choice

Which statement about the semiconservative replication of DNA is true?

Semiconservative replication produces daughter molecules that are identical to the parental molecule only if no mutations occur.

Both strands of the parental DNA are completely conserved in one daughter molecule.

Each daughter DNA molecule contains two newly synthesized strands.

Each daughter DNA molecule consists of one parental strand and one newly synthesized strand.

Verified step by step guidance

Understand the concept of semiconservative replication: during DNA replication, each of the two parental DNA strands serves as a template for the synthesis of a new complementary strand.

Recall that in semiconservative replication, the resulting daughter DNA molecules each contain one original (parental) strand and one newly synthesized strand.

Evaluate the given statements by comparing them to the definition of semiconservative replication: the statement that each daughter DNA molecule consists of one parental strand and one newly synthesized strand aligns with the concept.

Recognize that the statement about both strands of the parental DNA being completely conserved in one daughter molecule is incorrect because each daughter molecule only retains one parental strand, not both.

Note that the statement about daughter molecules containing two newly synthesized strands is incorrect, as one strand in each daughter molecule is always parental in semiconservative replication.
