WebHere, we'll take a look at four major types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), and regulatory RNAs. Messenger RNA (mRNA) Messenger RNA ( mRNA) is an intermediate between a protein-coding gene and its protein product. WebSmall RNAs (sRNAs) are short RNA molecules, usually non-coding, involved with gene silencing and the post-transcriptional regulation of gene expression. sRNA Sequencing (sRNA-seq) is a method that enables the in-depth investigation of these RNAs, in special microRNAs (miRNAs, 18-40nt in length).
