although more than 98% of the human genome is transcribed, most of these transcripts are not translated into proteins. rather, they are considered as non-coding rnas. micrornas (mirnas) are very short non-coding rnas approximately 22 nucleotides in length which regulate many key processes of cells such as growth, proliferation, differentiation, cell cycle, apoptosis (programmed cell death) and ...
