Question

Select the correct match
A.Matthew meselson-Pisum sativum
B.Alec Jeffreys- streptococcus Pneumoniae
C.Francois Jacob and Jacques monad- Lac operon
D.Alfred Hershey and Martha chase- TMV

Answer 1

We know that DNA is the genetic material in most organisms. It stores genetic information. Synthesis of new DNA from existing DNA Is called DNA replication. Transcription is the process of copying genetic information from DNA to RNA. The process by which proteins are derived from RNA is called translation.

Complete answer:
We know that Mathew meselson and Franklin Stahl are the scientists who proved experimentally that DNA replication is semiconservative in nature. They conducted several experiments in a bacteria called E.coli by growing them in a medium containing nitrogen salts that have a heavy isotope of nitrogen. They proved the semi-conservative nature of DNA replication first in bacteria and later, they demonstrated the same in higher organisms.
We know that DNA fingerprinting is a hybridization technique used to find out variations in individuals of a population at the DNA level. This process is also known as DNA typing. A scientist named Alec Jeffreys is known as the father of DNA fingerprinting. He studied the polymorphism present in DNA and developed this technique.
Jacob and Monad are the two scientists who Put forward the operon concept. They together conducted studies in bacteria E.coli. They elucidated a mechanism present in transcription level for gene regulation in E.coli bacteria. They stated that all metabolic reactions are controlled by a set of genes.
We all know about the experiments conducted by Alfred Hershey and Martha chase to prove DNA acts as the genetic material. They conducted experiments on viruses that are capable of delivering DNA to bacteria by infecting them. These viruses are called bacteriophages.
So, the correct answer is option C.

Note: We know that RNA also acts as genetic material in some organisms. We know that DNA is more stable than RNA as genetic material and it can resist mutations. But as RNA is highly unstable, it mutates at a faster rate.
