or proteins. I understand that primary, secondary, and tertiary structures are encoded by one gene each. However, I am not entirely sure if quaternary structures are encoded by one or multiple different genes. The reasons why I am a little confused is for two reasons. Firstly, quaternary structures are made up of more than one protein subunit (i.e. multiple polypeptides). Secondly, as I understand, Hemoglobin, for example, has different subunits, each of which is encoded by a different gene. Does this necessarily mean that all quaternary structures are composed of proteins encoded from different, separate genes? If quaternary subunits are encoded by different, separate genes, can those different genes be located on different loci, or are all of the subunits necessarily encoded by the different gene but its mRNA molecule is spliced differently?
