Ji wants to write an example of a frameshift mutation using the following sentence: THE CAT SAW THE RAT. Which sentence best shows a frameshift mutation?

This question lacks options, the options are:

A) THC ATS AWT HER AT

B) CAT THE SAW RAT THE

C) EHT TAC WAS EHT TAR

D) THE THE CAT SAW THE RAT

The answer is A

Explanation:

Mutations are generally any change that occurs to the nucleotide sequence of a gene. However, a FRAMESHIFT Mutation is a kind of mutation that changes/alters the reading frame of the nucleotide sequence. Frameshift mutations are caused when either a DELETION (removal of nucleotides) OR INSERTION (addition of nucleotides) MUTATION occurs.

In this question, Ji wants to write an example of a frameshift mutation using the following sentence: THE CAT SAW THE RAT. A frameshift mutation will delete or add nucleotide bases to the sequence. Hence, the sequence: THC ATS AWT HER AT best represents frameshift mutation because a deletion mutation has altered the reading of the sequence in three's.

Notice that the bases in options B, C and D are still read in three's.
