Answer - A

Semi-conservative model of replication involves the replication of DNA in all the familiar cells in such a way that each newly synthesized daughter cell contains a double helix with one new strand and one old strand.

Valeria Barry · Answer 2

The statement that is true of a semi-conservative model of replication is "each newly synthesized double helix of DNA contains one new strand and one old strand. The correct statement is A.
