What is RNA?

RNA is a ribonucleic acid that helps in the synthesis of proteins in our body. This nucleic acid is responsible for the production of new cells in the human body. It is usually obtained from the DNA molecule.

Ribonucleic acid (RNA) is a  molecule essential in various biological roles in  and of  RNA andare. Along with  and , nucleic acids constitute one of the four major essential for all known forms of  Like DNA, RNA is assembled as a chain of, but unlike DNA, RNA is found in nature as a single strand folded onto itself, rather than a paired double strand. Cellular organisms use  (mRNA) to convey genetic information (using the  of and  denoted by the letters G, U, A, and C) that directs synthesis of specific proteins. Many encode their genetic information using an RNA . A hairpin loop from a pre-mRNA. Highlighted are the (green) and the ribose-phosphate backbone (blue). This is a single strand of RNA that folds back upon itself. Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling or sensing and communicating responses to cellular signals. One of these active processes is, a universal function in which RNA molecules direct the synthesis of proteins on . This process uses  (tRNA) molecules to deliver to the ribosome, where (rRNA) then links amino acids together to form coded proteins.
