Answer 1

The Correct Option is A

This match highlights the fundamental contributions of each scientist to genetics and molecular biology. T.H. Morgan’s research on sex-linked inheritance provided important insights into the genetic basis of sex-linked disorders. Arthur Kornberg was awarded the No- bel Prize for his discovery of DNA polymerase, which is crucial for DNA replication. Nathan and Smith discovered the restriction endonucleases, essential for molecular cloning techniques, while Paul Berg developed the first methods of recombinant DNA technology, paving the way for genetic engineering.
