Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of mutation adds one or more base pairs?
A
Insertion
B
Substitution
C
Deletion
Explanation: 

Detailed explanation-1: -Insertion. Insertions are mutations in which extra base pairs are inserted into a new place in the DNA.

Detailed explanation-2: -Insertion An insertion, as related to genomics, is a type of mutation that involves the addition of one or more nucleotides into a segment of DNA. An insertion can involve the addition of any number of nucleotides, from a single nucleotide to an entire piece of a chromosome.

Detailed explanation-3: -A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three. This is important because a cell reads a gene’s code in groups of three bases when making a protein.

Detailed explanation-4: -In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping.
