Question
Chapter 13.4, Problem 1CC
Summary Introduction
To determine: The effect on the function of RNA polymerase as a result of the interaction of activator with a mediator.
Introduction: A mediator is a protein complex that is required during the process of transcription in eukaryotes whereas activators are regulatory transcription factors that are required to regulate the transcription process.

It will stop the translation once it encounters a stop codon D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protienarrow_forwardExplain the role of RNA polymerase.arrow_forward
