WebmicroRNAs microRNAs ( miRNAs) were among the first small regulatory RNAs to be discovered. A miRNA is first transcribed as a long RNA molecule, which forms base pairs with itself and folds over to make a hairpin. Next, the hairpin is chopped up by enzymes, releasing a small double-stranded fragment of about 22 22 nucleotides ^1 1. WebNational Center for Biotechnology Information

WebKey terms Structure of RNA DNA alone cannot account for the expression of genes. RNA is needed to help carry out the instructions in DNA. Like DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: WebReal-time PCR has become the method of choice for quantitating gene expression. It is simple and robust, and offers benefits such as a 9-log dynamic range, rapid results, sensitivity, specificity, and reproducibility that make other methods obsolete. Traditionally, the first steps in real-time PCR are to isolate and quantitate RNA.
