DNA replication is described as SEMI-CONSERVATIVE because:
ABoth daughter molecules have completely new strands
BDaughter molecules have completely conserved old strands
COne daughter is all old strands, the other is all new strands
DEach daughter has one old strand and one new strand
Answer & Solution
Correct answer: D. Each daughter has one old strand and one new strand
Semi-conservative means each daughter DNA molecule consists of ONE OLD (parental) strand + ONE NEW (newly synthesised) strand. Proved by the Meselson-Stahl experiment (1958).
