Learning Objective
I can describe how changes in DNA can lead to cancer.
- 1
A mutation is a change in genetic material, specifically within a nucleic acid like RNA or DNA.
- 2
Gene mutations include substitution, insertion, and deletion, with insertions and deletions potentially causing a frameshift mutation.
- 3
Chromosomal mutations include duplication, deletion, inversion, and translocation, which can occur during meiosis due to nondisjunction.
