What is semiconservative DNA replication?

Options

  1. AA replication process in which only one strand of DNA is conserved
  2. BA replication process in which both strands of DNA are conserved
  3. CA replication process in which both strands of DNA are replaced
  4. DA replication process in which only the newly synthesized strand of DNA is conserved

Correct answer

D. A replication process in which only the newly synthesized strand of DNA is conserved

Step-by-step solution

‘‘It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material’’ (Watson and Crick, 1953). The scheme suggested that 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 synthesized strand . This scheme was termed as semiconservative DNA replication
