Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a gene with six exons, explain how many different protein isoforms could theoretically be produced by alternative splicing. Assume that any combination of exons can be included or excluded.

💡 Hint: Think about combinations of choices for each exon.

Challenge 2 Hard

Propose a scenario where a malfunction in the RNAi pathway could lead to a specific disease. Describe the molecular mechanism involved.

💡 Hint: Consider the link between gene regulation and disease.
