Match List I with List II and select the correct answer using the codes given below the Lists: List I List II (Achievement in genetics) (Scientists) I. Discovery of transdiction and Conjugation in bacteria A) Khurana II. Establishing the sex-linked inheritance B) Kornberg III. Isolation of DNA polymerase form E. coli C) Lederberg IV. Establishing the complete genetic code D) Morgan E) Ochoa

The correct option is D because it correctly matches each scientist with their specific contribution to genetics: 1. Discovery of transduction and conjugation in bacteria: Joshua Lederberg, along with Norton Zinder and Edward Tatum, discovered these processes of genetic transfer in bacteria. Match: I-C. 2. Establishing the sex linked inheritance: Thomas Hunt Morgan used fruit flies to demonstrate that certain genes are linked to the sex chromosomes. Match: II-D. 3. Isolation of DNA polymerase from E. coli: Arthur Kornberg was the first to isolate this enzyme, which is essential for DNA replication. Match: III-B. 4. Establishing the complete genetic code: Har Gobind Khorana was instrumental in deciphering the genetic code and showing how nucleotides control protein synthesis. Match: IV-A. Therefore, the combination I-C, II-D, III-B, and IV-A is the correct sequence.
