What is the significance of histone modification in epigenetics?

• It changes the DNA sequence.

• It affects gene expression without changing the DNA sequence.

• It causes genetic mutations.

• It determines the parent of the organism.

What is the relationship between epigenetics and health issues?

• Epigenetics has no effect on health.

• Epigenetics can influence health issues.

• Health issues are only determined by genetics.

• Health issues are unrelated to epigenetics.

What occurs when genes are 'switched off'?

• Transcription is prevented

• Transcription takes place

• Genes are duplicated

• DNA is repaired
