Hint:

Understanding historical contributions to molecular biology is important for appreciating modern genetics

Answer 1

The Correct Option is A

Semiconservative replication of DNA was demonstrated by Meselson and Stahl Double helical structure of DNA was proposed by Watson Crick and Wilkins Adenosine Monophosphate synthesis was studied by H Khorana Synthesis of alanine tRNA was part of H Khoranas work
