Questions and Answers

What is the typical regulatory unit in prokaryotic gene expression?

  • A gene family
  • A DNA polymerase
  • A chromosome
  • An operon (correct)

Why is eukaryotic gene regulation more complex compared to prokaryotic regulation?

  • Eukaryotes have a more complex cell structure
  • Eukaryotes have a nucleus, which separates transcription and translation (correct)
  • Eukaryotes have a faster rate of gene expression
  • Eukaryotes have a smaller genome size

What is the primary difference between short-term and long-term eukaryotic gene regulation?

  • The number of genes involved
  • The response to environmental stimuli
  • The type of genes regulated
  • The duration of gene expression (correct)
