WebFunctions of giant polytene chromosomes: ADVERTISEMENTS: (1) Main function of the polytene chromosome is to carry genes which ultimately control physiology of an organism. These genes are formed of DNA molecules. (2) Shifting of heterochromatin in respect to euchromatin produces giant changes called position effects.
