|---|---|
| Back | - different sequence of bases in gene that codes for haemoglobin polypeptide sub-units - different primary structure and amino acid sequence of polypeptides - different H, ionic and disulfide bond positions on polypeptide chain - different specific tertiary structures - different quarternary structure and shape - different oxygen binding properties |
