Study Notes
Mutagens
- Mutagens are agents that induce mutations.
- Mutagens are classified into three types: physical, chemical, and biological.
Physical Agents
- X-rays
- Ultraviolet rays
- Gamma rays
- Very high temperatures
Chemical Agents
- Tar in cigarette smoke
- Mustard gas
- Nitrous acid
- Benzene
- Formaldehyde
- Asbestos
Biological Agents
- Some viruses (e.g., HPV)
- Food contaminants
- Mycotoxins from fungi
- Aflatoxin from contaminated nuts
- Chemicals in charred meat
Types of Mutations
- Gene Mutation: A change in the sequence of bases in one part of a DNA molecule.
- Chromosomal Mutation: Changes to the structure of a chromosome or the total number of chromosomes in a cell.
