Question

According to the conservative model of DNA replication, the original DNA double strand would:

Options

• Separate into two strands that each serve as templates

• Remain together while an entirely new double strand is synthesized

• Fragment into segments that are mixed in daughter molecules

• Replicate while remaining connected at the origin of replication

Answer 1

The conservative model proposed that the parental DNA strands would remain together as an intact unit, while a completely new double-stranded DNA molecule would be synthesized separately. This model was disproved by Meselson and Stahl's experiments.
