What is the function of the promoter region in a gene?
Correct Answer: The promoter region initiates transcription.
- Step 1: Understand that a gene is a part of DNA that contains instructions to make a protein.
- Step 2: Know that transcription is the process of copying the gene's instructions into a messenger molecule called RNA.
- Step 3: Identify the promoter region as a specific sequence of DNA located at the beginning of a gene.
- Step 4: Recognize that the promoter region acts like a 'start signal' for transcription.
- Step 5: Learn that RNA polymerase is an enzyme that binds to the promoter region to begin the transcription process.
