If ¹⁵N DNA replicated using conservative replication in ¹⁴N media,the outcome would be that new DNA has A) a single intermediate density. B) a lower density. C) only the higher density. D) one high density and one low density strand.

Question

Quizplus · Accepted Answer

Conservative replication involves the formation of two new double-stranded DNA molecules, with one molecule being completely newly synthesized and the other being completely conserved from the parental DNA molecule. Therefore, if ¹⁵N DNA replicates using conservative replication in ¹⁴N media, the outcome would be that one of the daughter DNA molecules would have an entirely low density (conserved from the parental molecule), while the other daughter DNA molecule would have an entirely high density (completely newly synthesized). Thus, the new DNA would have one high density and one low density strand, making option D the correct answer.
