What are mutations?

Back

Mutations are random changes in the DNA sequence that can lead to variations in traits.

What is a point mutation?

Back

A point mutation is a type of mutation where one base in the DNA sequence is replaced by another base.

What is a frameshift mutation?

Back

A frameshift mutation occurs when bases are added or removed from the DNA sequence, altering the reading frame.
