Interactive Quizzes

Quick quizzes to reinforce your learning

Question 1

What is the main function of transcription factors?

To start translation
To bind to DNA and regulate transcription
To degrade mRNA
To modify protein structure

💡 Hint: Think about what role they play in transcription.

Question 2

True or False: Alternative splicing can result in different proteins being produced from the same gene.

True
False

💡 Hint: Consider how genes can code for multiple isoforms.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A researcher is studying a gene that exhibits alternative splicing. If researchers discover additional exons that can be included, how might this affect protein diversity?

💡 Hint: Consider how different combinations of exons can result in various products.

Challenge 2 Hard

Given a scenario where a gene's enhancer region is mutated, resulting in diminished transcription factor binding, predict the potential outcome on protein levels.

💡 Hint: Think about the relationship between transcription factor binding and gene expression levels.
