Questions and Answers

What are the major differences between prokaryotic and eukaryotic cells?

  • Eukaryotic cells have a true nucleus, while prokaryotic cells do not. (correct)
  • Prokaryotic cells are usually larger in size compared to eukaryotic cells.
  • Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.
  • Eukaryotic cells have circular DNA, while prokaryotic cells have linear DNA.

What is the process of transcriptional control at the level of the genome?

  • Enhancing the process of translation
  • Methylation of DNA to prevent transcription (correct)
  • Formation of tRNA molecules
  • Splicing of exons and introns

What is the function and components of the eukaryotic cell cycle?

  • Interphase, metaphase, anaphase, telophase; controls protein synthesis
  • G1, S, G2, M phases; regulates cell growth and division (correct)
  • G0, G1, G2, M phases; governs energy production in the cell
  • Prophase, prometaphase, metaphase, anaphase; coordinates cell signaling
