- A Both resulting daughter molecules consist largely of newly synthesized strands
- B Each daughter molecule retains one parental strand and gains one new strand
- C Half of the nitrogenous bases are conserved while the other half are replaced
- D Mainly one of the two daughter molecules contains any original parental DNA
Correct answer: B. Each daughter molecule retains one parental strand and gains one new strand
Explanation: In semiconservative replication, each of the two daughter DNA molecules consists of one old (parental) strand and one newly synthesised strand.
