Questions & Step-by-Step Solutions

What is the role of RNA polymerase in transcription? (2021)
  • Step 1: Understand that transcription is the process of making RNA from DNA.
  • Step 2: Identify RNA polymerase as the enzyme that carries out this process.
  • Step 3: Know that RNA polymerase binds to a specific region of the DNA called the promoter.
  • Step 4: Realize that once bound, RNA polymerase unwinds the DNA strands.
  • Step 5: Understand that RNA polymerase reads the DNA template strand and synthesizes a complementary RNA strand.
  • Step 6: Remember that the RNA strand is built by adding RNA nucleotides that match the DNA sequence.
  • Step 7: Conclude that RNA polymerase continues this process until it reaches a termination signal, completing the RNA molecule.
