Smallest segment of genetic material affected by mutation is?

OPTIONS

(A) Recon
(B) Cistron
(C) Muton
(D) Exon

ANSWER

(C) Muton

EXPLANATION

Muton is the smallest unit of genetic material within a gene that can undergo mutation, historically defined as the smallest mutable unit. A recon is the smallest unit of recombination, a cistron corresponds approximately to a functional gene unit, and an exon is a transcribed region retained in mature RNA.
