Question

Which statement is/are not true about mitosis?
a) Mitosis is a process that duplicates and divides the nuclear contents only
b) Mitosis produces two daughter cells that contain the same number of chromosomes as the parent cell
c)Mitosis produces two daughter cells that contain the same kind of chromosomes as the parent cell
d)Mitosis uses a diploid parent cell to form daughter cells containing n chromosomes.

Answer 1

Hint: 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.

Complete answer:
 Mitosis is a process in which equational division occurs. The cells double the amount of chromosome by replication and then divide it into two daughter cells. they give rise to the genetically identical daughter cells which have the same number of chromosomes present in them. The process of mitosis is necessary for the growth of the organism and for the growth of the embryos because it is the only process that produces the same cells as that of the parent cell. The mitosis is divided into various stages like prophase, metaphase, anaphase and telophase. In the first three phases of the mitosis, the cell has doubled its chromosome and is ready for the nuclear division. By the start of the telophase, the nuclear division or the karyokinesis is completed and the cytokinesis starts. By the end of the telophase cytokinesis gets completed and two same kinds of identical daughter cells are formed.
So, the answer is ‘mitosis is a process that duplicates and divides the nuclear contents only’.

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.
