What is NOT a characteristic of transcription factors (TFs)? A) They influence the initiation of transcription. B) They are not required for RNA polymerase's binding to the promoter. C) They bind to specific DNA sequences. D) They are produced in the same chromosome they operate on.
Understand the Problem
The question is asking which option does NOT describe the characteristics of transcription factors (TFs). It requires knowledge of the role and functions of TFs in the process of transcription initiation.
Answer
D) They are produced in the same chromosome they operate on.
The final answer is D) They are produced in the same chromosome they operate on.
Answer for screen readers
The final answer is D) They are produced in the same chromosome they operate on.
More Information
Transcription factors can influence transcription initiation, bind to specific DNA sequences, and can act across different chromosomes, not necessarily being produced on the same chromosome where they operate.
Tips
A common mistake is assuming transcription factors must be produced on the exact chromosome where they perform their function, but they can be synthesized elsewhere and function over different genomic regions.
