Transcription and Splicing

• What is splicing?

  • removal of base sequences corresponding to introns; functional exons are joined together
• What is transcription?

  when pre-mRNA is spliced to form mRNA
• Explain the process of transcription

  1. helicase breaks hydrogen bonds
  2. one DNA strand acts as a template
  3. RNA nucleotides attract to the exposed bases
  4. RNA polymerase joins nucleotides
  5. pre-mRNA is spliced to remove introns
