Question 1.
What is epigenetics?
Show hintHide hint
Think about how genes can be turned on or off without changing the underlying code.
Question 2.
Which process usually represses gene expression?
Show hintHide hint
Consider what happens when a methyl group is added.
3Question 3.
What defines epigenetics?
- Changes in DNA sequence
- Heritable changes in gene expression
- Alteration of chromosomal structure
Show hintHide hint
Remember, it’s about expression, not alteration.
4Question 4.
True or false: Histone modification can both activate and repress gene expression.
- True
- False
Show hintHide hint
Consider the different types of histone modifications.
Question 5.
Design a hypothetical epigenetic therapy targeting a specific gene involved in neurodegenerative disease. What would be the mechanism used and why?
Show hintHide hint
Consider how changing gene expression can influence neurological health.
Question 6.
Critically evaluate the ethical implications of using epigenetic modifications in germline cells. What are the potential risks and benefits?
Show hintHide hint
Think about the balance between innovation in medicine and possible generational effects.
