Biochemists and molecular biologists, who have been in thefield for a couple of decades, would probably remember the timewhen it was a norm to term all RNA ‘junk’ if it did not translateinto a protein product. Gone are those days. The erstwhile ‘junk’RNA is now a much pursued and sought entity. The RNA moleculesthat do not code for any proteins; the ‘non-coding RNAs’, are now ahot topic in modern day research. Many non-coding RNAs arevery much functional in biological systems, and compensate fortheir inability to be translated into proteins through alternatemechanisms.
