The Correct Option is D
Solution and Explanation
To solve the given question, we need to match notable scientists or discoveries with their corresponding achievements or subjects in biology. Let's analyze each option to find the correct match.
- Alec Jeffreys - Streptococcus pneumoniae: Alec Jeffreys is known for developing techniques for DNA fingerprinting and DNA profiling, crucial for genetic studies and forensic biology. Streptococcus pneumoniae is unrelated to his work.
- Matthew Meselson and F. Stahl – Pisum sativum: Meselson and Stahl are famous for their experiment demonstrating the semiconservative replication of DNA. Pisum sativum (pea plants) was used by Gregor Mendel for his genetic experimentation, not by Meselson and Stahl.
- Alfred Hershey and Martha Chase – TMV: Hershey and Chase are known for their experiment with bacteriophages that confirmed DNA as the genetic material. Tobacco Mosaic Virus (TMV) is unrelated to their research.
- Francois Jacob and Jacques Monod – Lac operon: Francois Jacob and Jacques Monod are credited with discovering the Lac operon, a group of genes in bacteria that are controlled together. This was a pivotal discovery in molecular biology and gene regulation.
In conclusion, the correct match is Francois Jacob and Jacques Monod with the Lac operon. They conducted significant work on gene regulation mechanisms, which has had profound implications for understanding gene expression.
