RNA Structure

Polynucleotides

A polynucleotide stands as a biopolymer formed by covalently linked nucleotide monomers, arranged in a chain. Examples of such polynucleotides encompass DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), each manifesting distinct biological functions.

Structure of RNA

RNA is typically single-stranded, which allows it to fold into complex three-dimensional structures. This single-stranded nature enables RNA to form hairpins and loops, crucial for its function in the ribosome, in spliceosomes, and as tRNA.
