Challenge Problems
Push your limits with advanced challenges
The gene for a specific growth factor is found to be consistently silenced in certain cancer cells. Discuss how DNA methylation might contribute to this phenomenon and propose a method for reversing this silencing.
💡 Hint: Think about how methyl groups affect gene activity.
Suppose a new transcription factor is discovered that enhances the expression of a gene involved in heart disease. Discuss how this factor's pathway could be potentially targeted for therapeutic intervention.
💡 Hint: Consider how factors interact with other cellular pathways.
