Vedclass · Answer

(C) The original $DNA$ sequence is $ATG\ ATG\ ATG$.When a cytosine $(C)$ base is inserted at the beginning,the sequence becomes $C\ ATG\ ATG\ ATG$.This is an example of an insertion mutation.Since the reading frame is shifted by one base,the new codons formed are $CAT$,$GAT$,$GAT$,and the remaining $G$ base.Therefore,the resulting sequence is $CAT\ GAT\ GAT\ G$.

If the $DNA$ codons are $ATG\ ATG\ ATG$ and a cytosine base is inserted at the beginning,which of the following will result?
