After a mutation at a genetic locus the character of an organism changes due to the change in

Protein synthesis pattern

$RNA$ transcription pattern

Protein structure

$DNA$ replication

(AIPMT-2004)

Solution

(c)Changed proteins are formed in mutations due to the reason that $mRNA$ transcribed from the mutated gene and the abnormal $mRNA$ introduce different amino acids in the polypeptide chain formed with changed message.
