Question

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

• A. Transformation
• B. Transduction
• C. Semi-conservative DNA replication
• D. Central dogma

Answer 1

The correct option is C Semi-conservative DNA replication

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'
