Vedclass · Answer

(D) In the first mutation: $UAU\ ACC\ UAU$ changes to $UAU\ AAC\ CUA$. Here,the deletion of the first '$C$' in '$ACC$' causes a shift in the reading frame,resulting in a frame shift mutation.In the second mutation: $UUG\ CUA\ AUA$ changes to $UUG\ CUG\ AUA$. Here,the '$A$' in '$CUA$' is replaced by '$G$',changing the codon to '$CUG$'. Since a purine is replaced by another purine (or pyrimidine by pyrimidine),this is a transition mutation.Therefore,the mutations are frame shift and transition respectively. The correct option is $D$.

Identify the following point mutations in $mRNA$: $UAU\ ACC\ UAU$ to $UAU\ AAC\ CUA$ and $UUG\ CUA\ AUA$ to $UUG\ CUG\ AUA$.
