Abstract: Abstract: microRNA, one of the small molecular RNA family, is a very small section of non-coding RNA sequence, which can regulate several biological processes. This review tries to have a brief introduction on the progresses on microRNA study, such as the structure, the biogenesis, processing and the function
Key words: microRNA（miRNA）；Drosha；Dicer；siRNA
