Questions & Step-by-Step Solutions

What is the significance of the promoter region in a gene?
Correct Answer: Promoter region ka significance yeh hai ki yeh RNA polymerase ka binding site hota hai, jahan se gene ki transcription shuru hoti hai.
  • Step 1: Understand that genes are segments of DNA that provide instructions for making proteins.
  • Step 2: Know that transcription is the process where the information in a gene is copied to make RNA.
  • Step 3: Identify the promoter region as a special part of the gene located at the beginning.
  • Step 4: Realize that the promoter region has a specific DNA sequence that signals where transcription should start.
  • Step 5: Learn that RNA polymerase is an enzyme that binds to the promoter region to begin the transcription process.
  • Step 6: Conclude that without the promoter region, RNA polymerase would not know where to start, and the gene would not be transcribed.
