2. What is a mutagenic agent?
- Something that stops mutations
- Something that slows down the formation of tumours
- Something that increases the rate of a mutation
- Something that causes cancer
3. How does hypermethylation cause tumours?
- The tumour suppressor cells produce too much of the protein for cell division causing uncontrollable growth of tumours
- Transcription cannot happen when tumour suppressor genes are hypermethylated which means proteins for slowing down cell division aren't made. This causes uncontrollable cell division and tumours develop
- The proto-oncogenes act as oncogenes meaning the proteins for cell division are over-produce. This causes uncontrollable cell division
- The proto-oncogenes do not produce enough of the protein which slows down cell division meaning cell division becomes rapid and uncontrollable.
4. What do proto-oncogenes do?
- They produce proteins which make cells divide
- They produce enzymes that cause cell division
- They produce proteins which stop cell division
- They produce enzymes which cause apoptosis
5. How does oestrogen cause breast cancer?
- Oestrogen stimulates meiosis
- Oestrogen stimulates cell division
- Oestrogen causes cell division
- Oestrogen suppresses cell division
