Answer 1

The Correct Option is A

This overview highlights fundamental contributions to genetics and molecular biology. T.H. Morgan's research on sex-linked inheritance provided key insights into the genetic basis of sex-linked disorders. Arthur Kornberg, a Nobel Prize laureate, discovered DNA polymerase, which is critical for DNA replication. Nathan and Smith identified restriction endonucleases, essential for molecular cloning techniques. Paul Berg developed the first methods of recombinant DNA technology, initiating genetic engineering.
