Question

The protein complex that mediates the interaction between RNA polymerase II and regulatory transcription factors is called

a) Translocase
b) Activosome
c) Transcriptionosome
d) Mediator

Answer 1

The protein complex that mediates the interaction between RNA polymerase II and regulatory transcription factors is called the Mediator.

Step-by-step explanation:

The protein complex that mediates the interaction between RNA polymerase II and regulatory transcription factors is called the Mediator. In eukaryotes, the Mediator complex plays a crucial role in the recruitment and activation of RNA polymerase II, facilitating the initiation of transcription. It acts as a bridge between the transcription factors and RNA polymerase II, helping to bring them together at the promoter region of the gene.
