Micro RNA therapy is based on the premise that
A. miRNA molecules function to regulate gene expression, usually by initiating transcription; an over-production of miRNA can be replaced thereby promoting necessary protein production. B. miRNA molecules function to regulate gene expression, usually by promoting translation; a non-functional miRNA can be repaired thereby reducing unwanted protein production. C. miRNA molecules function to regulate protein production, usually by inhibiting translation; a hyperactive miRNA can be replaced thereby reducing unwanted proteins. D. miRNA molecules function to regulate gene expression, usually by inhibiting transcription; a non-functional miRNA can be replaced thereby reducing unwanted protein production.
Molecules that form channels that allow selected molecules to cross the membrane are called
1.recognition proteins. 2.transport proteins. 3.receptor proteins. 4.glycoproteins. 5.cell adhesion proteins.
