Show Hint
Benzer's terms:
- Muton: Single nucleotide (unit of mutation).
- Recon: Adjacent nucleotides (unit of recombination).
- Cistron: Gene (unit of function).
- Muton: Single nucleotide (unit of mutation).
- Recon: Adjacent nucleotides (unit of recombination).
- Cistron: Gene (unit of function).

Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of Benzer's terms: muton and recon.
Step 2: Detailed Explanation:
Seymour Benzer proposed the terms:
- Muton: The smallest unit of mutation (a single nucleotide).
- Recon: The smallest unit of recombination (any adjacent pair of nucleotides).
Thus, the muton is a single nucleotide, and the recon is any adjacent pair of nucleotides.
Other options:
- Single gene and any pair of genes (A): Incorrect.
- Single gene and any homologous pair of chromosomes (C): Incorrect.
- Single nucleotide and any single gene (D): Incorrect.
- Deletion mutants and any cross-over gene (E): Incorrect.
Thus, option (B) is correct.
Step 3: Final Answer:
Thus, the muton is a single nucleotide, and the recon is any adjacent pair of nucleotides, which corresponds to option (B).
