What is semiconservative DNA replication?

What is semiconservative DNA replication?
  1. A replication process in which only one strand of DNA is conserved
  2. A replication process in which both strands of DNA are conserved
  3. A replication process in which both strands of DNA are replaced
  4. A replication process in which only the newly synthesized strand of DNA is conserved

Solution

Semiconservative DNA replication is a replication process in which only the newly synthesized strand of DNA is conserved. During replication, the two strands of DNA separate and act as a template for the synthesis of new complementary strands. After replication, each DNA molecule has one parental and one newly synthesized strand.
