Question

explain mitosis 1 in detail

Answer 1

Mitosis is a type of Cell division.It is simply the division of the autosomal cells. In this process,the chromosomes of the cell are copied to make two identical sets of chromosomes and the nucleus divide into two identical nuclei. The cell divided by this process are identical in shape. The major purpose of mitosis is growth and replacement of worn out cells.

Answer 2

Answer:

• mitosis is the process of cell division of occuring in somatic cell.
• it is essential for the growth of the body.
• it is completed through to main step namely, karyokinesis (nuclear division) and cytokinesis (cytoplasmic division.)
• karyokinesis occur four steps
• profase ,metaphase, anaphase and telophase.

Prophase

• during this phase theoead like chromosome condense.
• the centrioles duplicate and move to the opposite pole of the cells
• the nuclear membrane and nucleus start disappearing.

Metaphase

• during metaphase the nuclear membrane completely disappear.
• chromosome complete condensation and become clearly visible along with sister chromatids.

Annaphase

• the centromere split and the sister chromatid are pulled apart in opposite direction with the help of spindle fibres.
• the separated sister chromatids react to opposite poles of the cell.

Telophase

• daughter chromosome Begin to decondense and the nuclear membrane is performed around each set of chromosome present at the poles.
• this result in the formation of two daughter nuclei.
• nuclear reappers in each daughter nucleus and the spindle ribens disappear completely.
• read the end of karyokinesis ,cytokinesis begin and as a result to new daughter cell are formed.
