Question

Identify and describe each phase of mitosis.

Answer 1

Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, in two separate nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components.

Answer 2

the question was identify the phases of mitosis and basically the defintion of the phases

Answer 3

I know what is but I don't know how to explain in english hehehe

Answer 4

o

Answer 5

there are four phases of mitosis 1)Prophase 2)Metaphase 3)Anaphase 4)Telophase

Answer 6

Pophase:
during early stage chromatin material condenses and becomes visible as thick coiled,thread like structures called chromosomes each chromosome at this stage is already doubled i,e consist of two chromatids. The chromatids are attached to each other at centromere. The nuclear membrane gradually disappears and at the same time centrosomes divides to form two centriols,each move towards the opposite pole of the cell and forms the spindle fibres.the centioles are absent in plant cells

Answer 7

Metaphase:
during this stage each chromosomes arranges itself on the equator of the spindle.Each chrosome is attached to separate spindle fibre by its centromere.

Answer 8

Anaphase:
in this phase the centromere of a chromosome divides and the chromatids of each chromosome separate from each other and begin to move towards opposite poles.In this way one set of the chromatids(each chromatid is now an independent chromosome) move towards one pole while the other set towards the other pole

Answer 9

Telophase:
this is a stage when the chromatids(now called chromosomes) reach the poles and their movement ceases. each pole receives the same number of chromosomes as were present in parent cell.The nuclear membrane is reformed around each set of chromosomes.In this way two daughter nuclei are formed in each cell.
Soon the cytoplasm of the cell also divides and two daughter cells arise.The nucleus of each daughter cell contains the same chromosome number as in their parent cell.In this way the daughter cells are exact copies of their parent cell.
