(ii) Genetic material should be able to express itself.
(iii) There are occasional changes or mutation in the structure and functioning of its genes, which are of permanent nature and inheritable.
It should be stable.
It should be same in both quantity and quantity in all cells of an individual.
All the property mentioned above are fulfilled by DNA, so DNA is the genetic material.
