The Search for Genetic Material

Question

	List – I		List – II
A)	Watson and Crick	i)	Established DNA as genetic material
B)	Messelson and Stahl	ii)	Model for Structure of DNA
C)	Jacob and Monad	iii)	Proved DNA replicates in semiconservative manner
D)	Hershey and Chase	iv)	Regulation of DNA expression

Easy

Solution

Watson and Crick gave double helical model to understand the structure of DNA. Messelson and Stahl proved semiconservative replication of DNA. Jacob and Monad discovered regulation of gene expression in Prokaryotes by proposing the operon concept. Hershey and Chase established DNA as genetic material in Bacteriophages.
