Question
Which of the following statements about RNA polymerase is incorrect?Group of answer choicesIt unwinds a short stretch of DNA.It synthesizes RNA from an RNA molecule from start to endIt detects termination signalsIt interacts with transcription factorsNone of the above
Solution
To determine which of the statements about RNA polymerase is incorrect, we will evaluate each statement one by one:
-
"It unwinds a short stretch of DNA": This statement is correct. RNA polymerase unwinds a short stretch of DNA to expose the template strand for RNA synthesis.
-
"It synthesizes RNA from an RNA molecule from start to end": This statement is incorrect. RNA polymerase synthesizes RNA from a DNA template, not from an RNA molecule.
-
"It detects termination signals": This statement is correct. RNA polymerase recognizes specific termination signals in the DNA sequence to know when to stop transcription.
-
"It interacts with transcription factors": This statement is correct. RNA polymerase interacts with transcription factors to initiate and regulate the transcription process.
Based on our evaluation, the incorrect statement is: "It synthesizes RNA from an RNA molecule from start to end."
