MCQ
$DNA$ replication is
  • A
    conservative and discontinuous.
  • ✓
    semi-conservative and semi-discontinuous.
  • C
    semi-conservative and fully discontinuous.
  • D
    dispersive
✓

Answer

Correct option: B.
semi-conservative and semi-discontinuous.
b
$DNA$ replication is the process in which a double stranded $DNA$ molecule is copied to produce two identical $DNA$ molecules. In $DNA$ replication each new strand is half the original parent strand (hence called semiconservative) and one strand is synthesized continuously and other discontinuous (hence called diccontinunus)
