The statement in the multiple-choice question is "RNA polymerase unzips the DNA strands and builds the mRNA in the 5' to 3' during transcription."
Let's break it down step by step:
1. RNA Polymerase: This enzyme is responsible for transcribing DNA into mRNA during the process of transcription.
2. Unzips the DNA Strands: RNA polymerase separates the two strands of DNA, allowing one of the strands to be used as a template for mRNA synthesis.
3. Builds the mRNA: The RNA polymerase adds complementary RNA nucleotides to the DNA template strand, forming an mRNA molecule.
4. 5' to 3' Direction: RNA polymerase synthesizes the mRNA in the 5' to 3' direction. This means that it reads the DNA template from the 3' end to the 5' end and synthesizes the mRNA in the opposite direction (5' to 3').
Therefore, the correct answer to the multiple-choice question is True. RNA polymerase does indeed unzip the DNA strands and build the mRNA in the 5' to 3' direction during transcription.
