the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,
- All organism are composed of one or more cells
- The cell is the structural and functional unit of life
- It is a de novo structure, that means it COULD arise from non living thing which was incorrect.
It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,
- Cells can arise only by a division of pre-existing cell. It is NOT a de novo structure.
Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

HOW DO VIRUSES CAUSE CANCER?
Viruses bring new genes into the cell.
Viral genes act in either of two ways:
1. Viral genes encode proteins that activate the cell
cycle to drive the cell into continuous cell division.
2. Viral genes encode proteins that act as inhibitors
of tumor suppressor proteins. (
End result is loss of control of the proteins that
regulate the cell cycle
