what are the properties of genetic material ? explain each.

Followings are the properties of genetic material:
1. It should be present in every cell.

2. It must contain all the biologically useful information in a stable form.
3. It should be able to store information in the coded form for the control of biological functions of the cells, and also to express its information.
4. It should show diversity corresponding to the variety existing in the organisms.
5. It should be able to replicate precisely, and then faithfully pass over its true copies to the successive generation.
6. It should also be capable of variations, i.e., recombination and mutation. Further, such variations must be stable and inheritable.
7. The genetic material should be able to generate its own kind and also new kinds of molecules.
8. It should be capable of differential expression so that the various parts of an organism may acquire specific form, structure and functions in-spite of having the same genetic material.
I hope it was helpful to u !!!
