Q184 / 200 · NEET 2002 · Zoology

Cancerous cells can be easily destroyed by radiations due to:

  • Correct answer
    A
    rapid cell division
  • B
    lack of nutrition
  • C
    fast mutation
  • D
    lack of oxygen

Solution

Cancer cells rapidly undergo mitosis. Cancer cells which divide rapidly are less organized than healthy cells. Cancerous cells can easily be destroyed by radiation due to the ability of radiations to kill cells is highest in the tissue with highest number of dividing cells. Hence, tumours are killed more rapidly by radiations.

Hence, the correct answer is option: 'A'.
