Question

This mutation results from the insertion of two nucleotides into the original sequence which causes the reading frame of the sequence to change this kind of mutation is known as

Answer 1

Frameshift mutation

Step-by-step explanation:

There are many different types of mutations in genetics, one such mutation is known as a frameshift mutation.

Codons are sequences of three nucleotides that determine the amino acid it codes for, and when something changes with these sequences, then we have a mutation.

In a frameshift mutation, nucleotides are added or deleted in such a way that the reading frame changes. For example:

If we have the nucleotide sequence- AUG UGC ACG UAC UUG CAG...

We can see that the reading frame reads three nucleotides per amino acid, however if an extra two nucleotides are added in a random location, then there is a shift- AUG UGC AUA CGU ACU UGC AG... (the underlined indicate the added nucleotides).

Now every amino acid after the frameshift mutation would be incorrectly coded for.

Answer 2

The answer would be frameshift mutation.

The frameshift mutation happens when insertion or deletion of a number of nucleotides that is not multiple of 3. The result will definitely cause a problem in the reading sequence.
In this case, there are insertions of two nucleotides and two is not multiple of 3.
