Vedclass · Answer

(C) The original sequence is $AAC\ GAC\ AGC\ GGC\ ACA\ AAA$. If the first base $(A)$ is deleted,the sequence becomes $ACG\ ACG\ AGC\ GGC\ ACA\ AA$. This is a frameshift mutation. However,in the context of this specific question,if we consider the deletion of the first base of the first triplet,the reading frame shifts entirely. Option $C$ is the most scientifically accurate description of a frameshift mutation,as the deletion of a single base changes every subsequent triplet codon,leading to a completely different sequence of amino acids in the resulting polypeptide chain.

The arrangement of $DNA$ has the triplet base sequence $AAC\ GAC\ AGC\ GGC\ ACA\ AAA$. Due to a mutation,the first base is deleted. What is the likely effect of this on the coding of the $DNA$ segment?
