Question

Which statement explains why DNA replication is described as semi-conservative? (A) Half of each original strand is conserved in each new molecule of DNA. (B) Half of the base sequence of each strand is conserved in each new molecule of DNA. (C) Only one strand of DNA is used as a template during replication. (D) The template for each new strand of DNA molecule is one strand of the original molecule

The two strands would separate and act as a template for the synthesis of new complementary strands. After the completion of replication, each DNA molecule would have one parental and one newly synthesised strand.
The Meselson-Stahl experiment confirmed that DNA replicated semi-conservatively.
