2

A
- Carcinogens
- X-rays

3
Q
What happens when a mutation occurs ?
A
A change in a codon could change a specific amino acid which makes a protein changing the protein as well
4

In non-coding DNA
5
Q
What are the different types of mutations ?

6
Q
What is a substitution mutation ?
A
When one of the bases is changed for another random base
7
Q
What is a insertion mutation ?

When an extra base is inserted into the sequence
( Worse than substitutions as amino acid chain is completely different )
