Solution
The correct option is C Beadle and Tatum
R.d. Kornberg
R.D Kornberg was awarded the Nobel Prize in 2006 for his work on the molecular basis of eukaryotic transcription.
Beadle and Tatum
Beadle and Tatum irradiated Neurospora crassa with X-ray which resulted in mutant genes that could not synthesise the specific enzymes required for nutrition. Thus they proposed the one-gene-one-enzyme hypothesis in 1948 which states that each gene encodes a single enzyme.
A.E. Garrod
Garrod laid the groundwork for establishing the molecular basis of inheritance. He was the first to attribute a biochemical role to genes and find a connection between metabolic disorders and the Mendelian laws of inheritance.
T.H. Morgan
Morgan established the chromosomal theory of heredity via his experiments on the fruit fly or Drosophila melanogaster.
Final answer
(B) Beadle and Tatum
