Question

Match List I with List II

List I List II
A. Frederick Griffith I. Genetic code
B. Francois Jacob & Jacques Monod II. Semi-conservative mode of DNA replication
C. Har Gobind Khorana III. Transformation
D. Meselson & Stahl IV. Lac operon

Choose the correct answer from the options given below:

Options

A.A-II, B-III, C-IV, D-I
B.A-IV, B-I, C-II, D-III
C.A-III, B-II, C-I, D-IV
D.A-III, B-IV, C-I, D-II

Solution

Sol. [Key Concept: Discoveries in molecular genetics]

Frederick Griffith–bacterial transformation (A–III); François Jacob and Jacques Monod–lac operon (B–IV); Har Gobind Khorana–work deciphering the genetic code using chemically synthesised RNA sequences (C–I); Meselson and Stahl–experimental demonstration of semiconservative DNA replication (D–II). Hence, option (4).
