Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

Just as for proteins, the structure of RNA occurs on multiple levels: nucleotide sequence (primary); intermediary structures that form when base pairs find their complements (secondary); and the ...

Intrinsically disordered proteins (IDPs) do not attain a stable secondary or tertiary structure and rapidly change their ...

tertiary structure, and often begins co-translationally. Protein folding requires chaperones and often involves stepwise establishment of regular secondary and supersecondary structures ...
