Review Questions

Control of gene expression in eukaryotic cells occurs at which level(s)?

  1. only the transcriptional level
  2. epigenetic and transcriptional levels
  3. epigenetic, transcriptional, and translational levels
  4. epigenetic, transcriptional, post-transcriptional, translational, and post-translational levels

Hint:

D

Post-translational control refers to:

  1. regulation of gene expression after transcription
  2. regulation of gene expression after translation
  3. control of epigenetic activation
  4. period between transcription and translation

Hint:

B

How does the regulation of gene expression support continued evolution of more complex organisms?

  1. Cells can become specialized within a multicellular organism.
  2. Organisms can conserve energy and resources.
  3. Cells grow larger to accommodate protein production.
  4. Both A and B.
