Question
CBSEENBI11025536

Select the correct statement related to mitosis.

  • Amount of DNA in the parent cell is first halved and then distributed into two daughter cells

  • Amount of DNA in the parent cell is first doubled and then distributed into two daughter cells

  • Amount of DNA in the parent cell is first halved and then distributed into four daughter cells

  • Amount of DNA in the parent cell is first doubled and then distributed into four daughter cells

Solution

B.

Amount of DNA in the parent cell is first doubled and then distributed into two daughter cells

Mitosis is a type of division in which the chromosomes replicate themselves and gets equally distributed into two daughter cells, i.e., the amount of DNA in this gets doubled first and then distributed into two daughter cells. This is actually a cloning in which daughter cells produced are identical to the parent cells and receive equal number of chromosomes.
