Question

One of the following is INCORRECT about cancer cells.

विकल्प

• They exhibit the property of contact inhibition.

• They are metastatic.

• They exhibit mass proliferation

• They are produced when cellular oncogenes of normal cells are activated. 

Answer 1

They exhibit the property of contact inhibition.

Explanation:

There is no contact inhibition in malignant cells. They spread from one body area to the next. Here, mutations render the tumour suppressor gene inactive while activating the proto-oncogene into an oncogene.
