Epigenetics starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Epigenetics. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

Describe the role of DNA methylation in gene silencing.
Explain how environmental factors can lead to epigenetic changes.
Explain how epigenetic changes can be reversed.
Explain the difference between genetic and epigenetic changes.
