Questions & Step-by-Step Solutions

What is the function of a promoter in a recombinant DNA molecule? (2023)
  • Step 1: Understand that a promoter is a specific part of DNA.
  • Step 2: Know that the promoter is located at the beginning of a gene.
  • Step 3: Learn that the promoter's main job is to signal the start of transcription.
  • Step 4: Realize that transcription is the process where DNA is copied to make RNA.
  • Step 5: Understand that when RNA is made, it can lead to the production of proteins, which are important for the cell.
  • Step 6: Conclude that the promoter is essential for gene expression, meaning it helps the gene to be turned on and used by the cell.
