(i) Not all proteins are enzymes. For example, some, like the proteins which form silk or hair, are structural. These non-enzymic proteins also need genes to specify them.
(ii) Some proteins (for example, haemoglobin) are formed by bringing together in the cytoplasm of the cell two or more components determined by different genes.
(iii) It is known that in bacteria some genes act only to 'regulate' the activities of other genes and the same is likely to be true in higher animals and plants.
