Vedclass · Answer

(A) The genetic code is read in triplets (codons). $A$ mutation in the first base of the $DNA$ segment $ATGACCAGGACCCCAACA$ will alter the first codon ($ATG$ to a different codon). Since the reading frame of the subsequent codons is determined by the sequence of bases,a change in the first base will lead to a change in the first codon,which subsequently alters the entire sequence of amino acids translated from this $DNA$ segment. This is known as a frameshift mutation or a missense mutation depending on the nature of the base change,but in this specific context,it results in a complete change in the type and sequence of amino acids.
