Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

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 challenges.

Question 1

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.

Question 2

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.
