Micro RNA (miRNA)
Micro RNA (miRNA) is one class of low molecular weight RNA(about 21 nucleotides long) which is found in eukaryotic cells. Like mRNA, miRNA is synthesised by RNA polymerase II but it's non-protein encoding RNA . Micro RNA molecules are complementary to mRNA molecules. They can bind to mRNA molecules and inhibit their translation resulting in a loss of gene expression.
