Vedclass · Answer

(C) In frame shift mutation,the reading frame of the base sequence shifts laterally either in the forward direction due to the addition of one or more nucleotides or in the backward direction due to the deletion of one or more nucleotides.In base pair substitution,a single base pair is replaced by another,which also results in a change of the nucleotide sequence.Since both processes alter the nucleotide sequence within a gene,the correct answer is both $(a)$ and $(b)$.

Column-$I$	Column-$II$
$(a)$ Exon	$(I)$ Non-coding sequence
$(b)$ Intron	$(II)$ Coding sequence
$(c)$ Genetic code	$(III)$ Nucleosome
$(d)$ $DNA$ packaging	$(IV)$ Nirenberg,Khorana and Matthaei
