Question
The mutation in which an extra base pair is inserted in the DNA sequence is called
- Insertion
- Frame shift mutation
- Deletion
- Addition
Hint:
Insertion is the addition of one or more nucleotide base pairs into a DNA sequence.
The correct answer is: 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.
- This can often happen in microsatellite regions due to the DNA polymerase slipping.
