Answer:
Mutations, Point mutations, Gneome editing
Step-by-step explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke
A point mutation is a change to single DNA letter. They fall into three categories: Missense mutations cause a single amino acid change in the protein
Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism's DNA.
