Yоu discоver а new regulаtоry pаthway that modulates a fungal defense mechanism in an obscure bacterial group. Given the roles of the different RNAs and proteins described below, select the most logical outcome of each condition or manipulation. Funk1 (Fungus killer 1) is a secreted defense peptide that causes rapid cell death in Penicilium fungi (who secrete penicillin). miRNA2 is a micro RNA that facilitates Funk1 translation by base pairing within the 5' untranslated region, preventing the formation of a hairpin that otherwise blocks the Kozak sequence. Fureg (Funk1 regulator) is a protein that binds miRNA2 in the absence of penicillin molecules. If penicillin is present in trace amounts and binds Fureg, this changes Fureg conformation such that it releases miRNA2. Penicillin is an antibiotic that is naturally produced and secreted by fungi in the genus Penicilium. (They secrete it to kill bacteria because they compete with bacteria for resources). Fureg proteins, Funk1 mRNA, and miRNA2 molecules are all constitutively expressed and are normally present in equal numbers in these bacterial cells. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A mutation is introduced into miRNA2 such that it can no longer bind Funk1 mRNA. This should result in [blank1]. A mutation is introduced into the Funk1 gene such that the Kozak sequence is in-tact, but the hairpin can no longer form. This should result in [blank2]. Experimental overexpression (10x dose) of miRNA2 should result in [blank3]. A mutation is introduced to the gene encoding Fureg such that it can no longer bind miRNA2. This should result in [blank4].
