Question: What is the function of RNA polymerase during transcription?

Options:

  1. To replicate DNA
  2. To synthesize RNA from a DNA template
  3. To splice RNA
  4. To translate mRNA into protein

Correct Answer: To synthesize RNA from a DNA template

Solution:

RNA polymerase synthesizes RNA by transcribing the genetic information from a DNA template.

Questions & Step-by-Step Solutions

What is the function of RNA polymerase during transcription?
  • Step 1: RNA polymerase is an enzyme that helps in the process of transcription.
  • Step 2: Transcription is when the information in DNA is copied to make RNA.
  • Step 3: RNA polymerase binds to a specific region of the DNA called the promoter.
  • Step 4: Once bound, RNA polymerase unwinds the DNA strands to access the genetic information.
  • Step 5: RNA polymerase reads the DNA template strand and starts to build a complementary RNA strand.
  • Step 6: As it moves along the DNA, RNA polymerase adds RNA nucleotides one by one to form the RNA molecule.
  • Step 7: This process continues until RNA polymerase reaches a termination signal in the DNA.
  • Step 8: Once the RNA strand is complete, RNA polymerase releases the newly formed RNA molecule.
