Conservative DNA replication is a hypothetical model that suggests the complete parental duplex DNA strands remain intact and unchanged after replication. In this model, the two parental strands remain together (conserved) and serve as templates for the synthesis of two new strands, resulting in one fully conservative duplex and one fully newly synthesized duplex.
On the other hand, semi-conservative DNA replication is the currently accepted model. It states that during replication, the parental DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. Therefore, each resulting DNA molecule contains one original (conserved) strand and one newly synthesized strand.
To summarize, conservative replication proposes the preservation of two parental strands, while semi-conservative replication involves the separation of parental strands and the formation of two new strands, one conserved and one synthesized.
