Question

Endomitosis is
A) mitosis without a nucleus
B) mitosis within the nucleus
C)frequent mitosis
D)mitosis in the uterine wall

Answer 1

Hint: Endomitosis is a condition in which the nuclear division does not take place. This leads to an increase in the amount of the chromosome number in the cell. This condition leads to an increase in the number of the ploidy of the cells.

Complete answer:
The endomitosis is a condition in which the mitosis occurs without the nucleus. The amount of the genetic material doesn’t get divided into two cells and remains in one cell only. This leads to an increase in the amount of the genome of the cell. Endomitosis results in the polyploidy in the cells.

Additional information: During the start of the mitosis the chromosome condenses and prepares themselves to be divided among the two cells. This leads to the disappearance of the nuclear membrane and then the separation of the chromosome takes place. At the end of the mitosis the nuclear membrane reappears and then the chromosomes decondense themselves. The division of the nuclear material in the cell is called karyokinesis. The cell undergoes various cell stages in which it is grown and then is prepared for the further division. The parent cell usually divides and then forms two daughter cells. the genetic material is doubled and then divided equally among the two cells formed.

So, the answer is option ‘A’ i.e, ‘mitosis without nucleus’.

Note: During mitosis, the cell divides completely and its content is also divided equally among the daughter cell formed. The cell after the division usually leads to further growth and again the division of those cells. some of the cells after some time go into the resting phase. In that phase, they don’t undergo the process of division.
