Molecular basis of heredity · Zoology

DNA replication is described as semi-conservative because:

  1. DNA is fully conserved during transcription of genes
  2. Each new DNA molecule contains one parental strand
  3. Replication occurs only once
  4. Only half the DNA is replicated
Show answer and explanation

Correct answer: Each new DNA molecule contains one parental strand

In semi-conservative replication, each daughter DNA molecule contains one original strand and one newly synthesized strand. This was demonstrated by Meselson and Stahl.
