Question

match each stage of transcription to its description.
termination initiation elongation
rna polymerase moves down the dna and pairs rna nucleotides along the template strand.
rna polymerase binds to a promoter and unzips a section of dna.
rna polymerase reaches a terminator, where the new mrna strand detaches from the dna.

Explanation:

1. Elongation is the stage where RNA polymerase synthesizes the RNA strand by adding complementary nucleotides as it travels along the DNA template.
2. Initiation is the starting stage where RNA polymerase attaches to the DNA promoter and unwinds the DNA double helix to begin transcription.
3. Termination is the final stage where RNA polymerase encounters a terminator sequence, and the newly formed mRNA is released from the DNA template.

Answer:

• RNA polymerase moves down the DNA and pairs RNA nucleotides along the template strand. → elongation
• RNA polymerase binds to a promoter and unzips a section of DNA. → initiation
• RNA polymerase reaches a terminator, where the new mRNA strand detaches from the DNA. → termination
