Select the correct match:

Options

  1. AMathew Meselson and F. Stahl - Pisum sativum
  2. BAlfred Harshey and Martha Chase - TMV
  3. CAlec Jeffreys - Streptococcus pneumonia
  4. DFrancois Jacob and Jacques Monod - Lac operon

Correct answer

D. Francois Jacob and Jacques Monod - Lac operon

Step-by-step solution

Francois Jacob (a geneticist) and Jacques Monod (a biochemist) proposed a model of gene regulation, known as operon model in bacteria in 1961. Operon is a co-ordinate group of genes such as structural gene, operator gene, promoter gene, regulator gene which function together and regulate a metabolic pathway as a unit, e.g., lac operon, trp operon, ara operon, his operon, val operon etc. Matthew Meselson and F. Stahl discovered the semi-conservative model of DNA replication in E. coli . Alfred Hershey and Martha Cha
