Questions and Answers

What is the ultimate measure of the expression of a protein-coding gene?

  • The number of exons in the primary transcript
  • The amount of functional protein produced (correct)
  • The amount of RNA transcript produced
  • The number of introns in the primary transcript

    • What is an example of a regulatory mechanism that operates at the RNA-processing level?

  • Transfer RNA (tRNA) processing
  • Ribosomal RNA (rRNA) processing
  • Alternative RNA splicing (correct)
  • mRNA translation

    • How does alternative RNA splicing affect gene expression?

  • It produces different mRNA molecules from the same primary transcript (correct)
  • It decreases the stability of mRNA molecules
  • It increases the number of exons in mRNA molecules
  • It reduces the binding of regulatory proteins to primary transcripts
