What is the role of RNA polymerase in gene expression?
Correct Answer: RNA polymerase synthesizes RNA from a DNA template.
- Step 1: Understand that genes are segments of DNA that contain instructions for making proteins.
- Step 2: Know that gene expression is the process of turning these DNA instructions into functional proteins.
- Step 3: Learn that RNA polymerase is an enzyme that plays a key role in this process.
- Step 4: Recognize that during transcription, RNA polymerase binds to a specific region of the DNA where a gene is located.
- Step 5: Understand that RNA polymerase then unwinds the DNA strands and reads the DNA sequence.
- Step 6: Realize that RNA polymerase synthesizes a complementary RNA strand using the DNA template.
- Step 7: Finally, know that this newly formed RNA can then be used to make proteins, completing the gene expression process.
