Which of the following is a way a cell uses to stop the function of one of its own proteins? (Choose all that apply) A. Close the chromatin around a gene, so that transcription factors can't bind. B. Make a mutation in the first exon. C. Make a nonsense mutation in the first exon after the start site. D. Degrade RNA polymerase so it can't transcribe the gene. E. Degrade an mRNA transcript once it has been made, via microRNAs. F. Inhibit transcription of that gene – via changes in transcription factors (trans-acting molecules) that function at the enhancer. G. Inhibit transcription of that gene – via mutations at the enhancer. H. Degrade an mRNA transcript once it has been made, via microRNAs. I. Sequester the mRNA for that gene from ribosomes. J. Stop the protein's function, by expressing another protein that is an antagonist.
