Questions and Answers

What is transcription-translation coupling?

  • A process where translation occurs before transcription
  • A process where transcription and translation occur in separate compartments
  • A mechanism of gene expression regulation where mRNA stability is affected by transcription
  • A mechanism of gene expression regulation where mRNA synthesis is affected by concurrent translation (correct)

    • In prokaryotes, when are mRNAs translated?

  • Before transcription starts
  • While they are being transcribed (correct)
  • After transcription is complete
  • In a separate cellular compartment from the site of transcription

    • What is the significance of transcription-translation coupling in bacteria?

  • It has no significant role in bacterial gene expression
  • It only affects the rate of transcription
  • It is essential for genome integrity, termination of transcription, and control of mRNA stability (correct)
  • It primarily influences the process of DNA replication
