What is RNA?

RNA elements are single stranded nucleic acids made up of nucleotides. RNA plays a serious role in protein synthesis the way it is mixed up in transcription, decoding, and translation from the genetic code to generate proteins. RNA stands for ribonucleic acid and like DNA, RNA nucleotides comprise three components:
A Nitrogenous Base
A Five-Carbon Sugar
A Phosphate Group
RNA nitrogenous angles include adenine (A), guanine (G), cytosine (C) and uracil (U). The actual five-carbon (pentose) sugar in RNA will be ribose. RNA molecules tend to be polymers of nucleotides joined together by covalent bonds between the phosphate of one nucleotide plus the sugar of another. These linkages tend to be called phosphodiester linkages.

Although single stranded, RNA just isn't always linear. It can fold into complex three dimensional shapes and style hairpin loops. While this occurs, the nitrogenous bases bind together. Adenine pairs using uracil (A-U) and guanine pairs using cytosine (G-C). Hairpin loops may be observed in RNA molecules like messenger RNA (mRNA) and transfer RNA (tRNA).
