When RNA polymerase reaches a terminator, what happens?
A
It immediately falls off the DNA sequence
B
It is marked by a protein that removes it from the DNA
C
Phosphates are removed from the polymerase tail, which cause it to remove from the DNA
D
It remains on the DNA strand, but does not transcribe
Verified step by step guidance1
Understand the role of RNA polymerase in transcription: RNA polymerase is an enzyme responsible for synthesizing RNA from a DNA template during transcription.
Identify what a terminator sequence is: A terminator is a specific sequence in the DNA that signals the end of transcription.
Explore the process of transcription termination: When RNA polymerase reaches the terminator sequence, it must stop transcribing and detach from the DNA.
Consider the mechanisms of RNA polymerase detachment: In eukaryotes, phosphorylation of the RNA polymerase tail is involved in its regulation. Dephosphorylation can lead to detachment from the DNA.
Evaluate the options given: Compare the provided options with the known mechanisms of transcription termination to determine which one aligns with the scientific understanding of RNA polymerase detachment.
