Question

Read the following statements regarding "Regulation of cell division” and identify the incorrect statement(s).

I. Regulation of cell division is a natural and an inherited property of a cell.

II. Contact inhibition is a method of regulation of cell division.

III. Regulation of cell division can also be inhibited by anchorage dependence of a cell.

IV. Anchorage dependence and contact inhibition increase the growth of cells and ensure that high cell density is maintained at all times.

• A. I & II
• B. II $\&$ III
• C. III $\&$ I
• D. IV only

Answer 1

The correct option is D IV only

Anchorage dependence and contact inhibition limit and do not increase the growth of cells. This ensures that the appropriate cell density and cell-to-cell contacts are maintained in the body.
