RNA interference (RNAi) also called post transcriptional gene silencing (PTGS), is a biological process in which RNA molecules inhibit gene expression, typically by causing the destruction of specific mRNA molecules. Two types of small ribonucleic acid (RNA) molecules: microRNA (miRNA) and small interfering RNA (siRNA) - are central to RNA interference.

Zinc fingers function as interaction modules that bind DNA, RNA, proteins, or other small, useful molecules.

Correct Option: C

Zinc fingers function as interaction modules that bind DNA, RNA, proteins, or other small, useful molecules.

While DNA contains deoxyribose, RNA contains ribose (in deoxyribose there is no hydroxyl group attached to the pentose ring in the 2′ position). These hydroxyl groups make RNA less stable than DNA because it is more prone to hydrolysis.

Commonly used reporter genes that induce visually identifiable characteristics usually involve fluorescent and luminescent proteins. Examples include the gene that encodes jellyfish green fluorescent protein (GFP),
which causes cells that express it to glow green under blue light, the enzyme luciferase, which catalyzes a reaction with luciferin to produce light, and the red fluorescent protein from the gene dsRed.

Chloramphenicol binds to the peptidyl transferase enzyme to inhibit transfer of the growing polypeptide to the next amino acid occupying the “Acceptor” site. Norfloxacin is a nalidixic acid analogue and one of the most potent DNA gyrase inhibitors. Puromycin is a secondary metabolite of Streptomyces alboniger that blocks protein biosynthesis. Puromycin is a structural analogue of the 32 end of aminoacyl-transfer RNA. Rifampicin inhibits bacterial RNA polymerase by binding to the beta subunit of RNA polymerase.
