Question

Nobel Prize to A. Kornberg and S. Ochoa was given for

• A. Biological synthesis of DNA and RNA.
• B. Theory of natural selection.
• C. Mutation theory.
• D. One gene one polypeptide chain theory.

Answer 1

Answer: (A)

• Kornberg and S. Ochoa were awarded the noble prize for the discovery of the mechanisms of the biosynthesis of DNA and RNA.
  
• Theory of natural selection was proposed by Charles Darwin as an explanation of adaptation and selection. He defined natural selection as the principle by which each slight variation if useful is preserved.
  
• Mutation theory was proposed by Hugo de Vries. He proposed that living organisms can develop changes to their genes that greatly affect the organism and can be passed onto the next generation and lead to the development of the new species.
  
• One gene one polypeptide chain theory was proposed by George Beadle. He stated that each gene is responsible for the synthesis of a single polypeptide.
  

So, the correct option is 'Biological synthesis of DNA and RNA'.
