MicroRNA is defined as noncoding small RNAs plying major role in gene regulation at post transcription level. Mature microRNA contains 22 nucleotide and shot in length. miRNAs shows expression in cancer diagnosis. Its Biogenesis involved as, Pri-microRNA is transcribed by RNA polymerase 11 after that precursor microRNA is formed by Drosha and dicer is involved to form mature miRNA of 22 nucleotide. For microRNA Proliferation Real time PCR is used. What is microRNAs or miRNA…
