miRNA is a small non-coding RNA molecule of 20â€“30-nucleotide length, and it plays an important role in gene regulation. As it is partially complementary to messenger RNA (mRNA), it serves a major function of down-regulating the gene expression, which makes it a key controller of important cellular functions. miRNAs are associated with pathological processes such as viral infections, autoimmune diseases, and carcinogenesis. Thus, extensive research is being conducted to identify new miRNAs...Read more
