MicroRNA ( miRNA) is small RNA of 22 nucleotides ( nt) in length that play important roles in regulating gene expression and biological processes.This review tried to have a brief introduction on the progresses of miRNA discovery and formation, including three steps of transcription, assemble processing and function complex processing.Regulating effect of miRNA in growth and development, stress adaption, its formation ways was analyzed.
