RNA is a type of nucleic acid that plays a role in a wide range of biological processes in all living organisms, including protein synthesis and gene regulation. RNA is made up of a single strand of nucleotides, which are molecules made up of a nitrogenous base, a ribose sugar, and a phosphate group. RNA molecules can vary in size and shape and they can form specific three-dimensional structures that are important for their function. For example, the secondary structure of tRNA is crucial for its ability to bind to specific amino acids. The tertiary structure of rRNA is important for its role in protein synthesis.
