Solution

The correct option is C Muton
1) Recon: They are locations within a gene which participate in recombination. There is a minimum distance between recons within a gene, and recombination cannot occur within a recon. The term “recon” is a unit of recombination.
2) Cistron: It is the largest element in a gene which encodes a polypeptide during protein synthesis.
3) Muton: the smallest element of genetic material capable of undergoing a distinct mutation, usually identified as a single pair of nucleotides.
4) An exon is any part of a gene that will encode a part of the final mature RNA produced by that gene after introns have been removed by RNA splicing.

So, the correct answer is 'Muton'.
