Choose the correct answer from the alternatives given : Which of the following phenomena was experimentally proved by Meselson and Stahl?

ATransformation
BTransduction
CSemi-conservative DNA replication
Correct Answer
DCentral dogma

Solution

The Meselson and Stahl experiment was an experiment to prove that DNA replication was semi-conservative and it was first shown in Escherichia coli and subsequently in higher organisms, such as plants and human cells. Semi-conservative replication means that when the double-stranded DNA helix was replicated, each of the two double-stranded DNA helices consisted of one strand coming from the parental helix and one is newly synthesized.
So, the correct answer is 'Semi-conservative DNA replication'
