(Theme 5) You are studying the role of a gene called stop. When expressed, stop appears to inhibit cellular processes controlled by another gene, Bisc219. To probe the molecular mechanism of stoP-mediated regulation of Bisc219, you begin by assaying bisc219 expression at the mRNA and protein levels. Your results are shown below. long short bisc219 mRNA stop no stop expressed | | long short Bisc219 protein stop no stop expressed a) Propose and briefly explain a specific molecular mechanism through which stop could operate, assuming that stop encodes a small RNA. Your answer should specify a specific molecular interaction(s) involved in gene expression that is/are disrupted. b) Propose and briefly explain a different molecular mechanism through which stop operates, now assuming that stop encodes a protein.
