• B. Alec Jeffreys - Streptococcus pneumoniae
• C. Francois Jacob and Jacques Monod - Lac operon
• D. Alfred Hershey and Martha Chase - TMV

Answer 1

The correct option is C Francois Jacob and Jacques Monod - Lac operon

1. Mathew Meselson and Franklin Stahl were the first to prove semiconservative replication of DNA in the bacterium Escherichia coli.

2. Alec Jeffreys was a British geneticist who developed the technique of DNA fingerprinting or DNA profiling.

3. Francois Jacob and Jacques Monod discovered the Lac operon in Escherichia coli and explained the protein synthesis regulation in prokaryotes.

4. Alfred Hershey and Martha Chase proved that DNA is the genetic material that is passed or inherited from one generation to next generation.
