... the protein was first created? Say, for example, you have the covalent bonds (along the entire primary structure) that form first, followed by disulphide bonds. What if a single disulphide bond were to form first, before all the covalent bonds had finished creating the primary structure? Is ...

... bonds are in quaternary structure yet! So it isn't a need to go on secondary structure as I wrote. The quaternary structure is supported by ionic, disulphide, van der Valse and hydrogen bonds. But hydrophobic bonds appear just in tertiary structure. So according to sequence I wrote, answer would ...
