Study Notes
Mutagenicity
- A mutagen is a chemical that causes an increase in growth due to mutations.
- If a chemical causes lower growth compared to the control group, it is not a mutagen.
- Mutagens increase growth by causing mutations in histidine, which then grow.
Direct and Indirect Acting Mutagens
- A mutagen can be direct or indirect acting.
- Pro-mutagen is a non-direct acting mutagen that needs to be metabolized first before it can convert histidine to its mutated form (his+).
Note on Research
- Rozaini conducted research on mutagenicity from 2009 to 2012.
