- Which of the following statements best describes the promoter of a protein-coding gene? A. The promoter is a protein that recruits RNA polymerase. B. The promoter is part of the RNA molecule itself. C. The promoter is a site found on RNA polymerase. D. The promoter contains the AUG start codon. E. The promoter is a nontranscribed region of a gene.arrow_forwardIf a cell's DNA was mutated such that it lost the promoter of a gene, you would expect: a. That ribosomes wouldn’t bind to that gene b. No effect since the promoter doesn't have any coding information for the amino acids in the polypeptide c. Ribosomes would never stop translating that gene d. Transcription factors for that gene would no longer bind to activate expression of that gene e. tRNA would no longer bind to the codons of that genearrow_forwardIf a mutation deletes the promoter in a eukrayotic gene, which of the following most accurately describes its consequence?
