Question

Who among the following propounded the terms muton, cistron, and recon?

• A. J. Lederberg
• B. W. Ingram
• C. Bateson
• D. S. Benzer

Hint:

J. Lederberg's contribution to genetics includes proposing the functional roles of muton, cistron, and recon in relation to genetic material.

Answer 1

The Correct Option is A

Step 1: Understanding the terms.
The terms "muton," "cistron," and "recon" were introduced by J. Lederberg. These terms are used in the field of genetics, particularly in the context of gene structure and function.
Step 2: Analyze the options.
- J. Lederberg: He was the scientist who first proposed these terms to describe the functional units of genes and genetic material. - W. Ingram: Known for his work on the molecular genetics of hemoglobin but did not coin these terms. - Bateson: A prominent biologist known for his work on inheritance but not the coining of these terms. - S. Benzer: Known for his work in genetic recombination and the molecular genetics of bacteriophages but not for the terms muton, cistron, and recon.
Step 3: Conclusion.
The correct answer is J. Lederberg, who introduced the terms "muton," "cistron," and "recon."
Final Answer: \[ \boxed{J. \; Lederberg} \]
