Questions & Step-by-Step Solutions

What is the role of the promoter in transcription?
  • Step 1: Understand that transcription is the process where DNA is used to make RNA.
  • Step 2: Know that a promoter is a specific sequence of DNA located at the beginning of a gene.
  • Step 3: Recognize that the promoter acts like a signal or a marker that tells the cell where to start making RNA.
  • Step 4: Learn that RNA polymerase is the enzyme that reads the DNA and makes RNA.
  • Step 5: Realize that RNA polymerase binds to the promoter to begin the transcription process.
