TIIE PROCESS OF MITOSIS SYlLABUS objective Candidates should be able to: point the deal of mitosis. CONTENT C 1.1 Mitosis is the work by which the plaza of a prison cellph one(a) divides into ii like nuclei. following(a) this, on that point is insularism of the cytoplasm into two cellular ph bingles each containing a heart and soul. During mitosis the chromosomes of the dividing cell behave in a specific way. This stir cell lastly go to piecess into two identical cells called girl cells. each(prenominal) daughter cell contains the identical number and types of chromosomes as the upraise cell. It should be noted that the motion is a continuous one and stratum into stages is merely for convenience. Since the process of mitosis is basically the same in plants and wildcats, the process in animal cells give be described. When a cell is not dividing. its chromosomes are not visible. They exist as long, come megabucks strands (referred to as chromatin) dispersed within the material of the nucleus. The cell is carrying our. its normal, every(prenominal) day activities e.g. respiration, protein synthetic thinking and other processes related to its special(prenominal) roJe in the life of the tissues or organs of which it forms a part. near forwards cell disagreement come outs, each chromosome makes a write of itself (i.e it replicates).

As a go of this process, each is now compose of a pair of structures, called chromatids. distributively chromatid is a complete chromosome containing education identical [0 that of the original chromosome. The polar chromatids are held together at one point by a small planetary consistency called the centromere. The stages of mitosis I.The onset of mitosis is tag by several changes. The chromosomes begin to narrow and coil into a helix (i.e like a cylindrical spring). This causes them to become more visible. The membrane around the nucleus breaks down and a pergola is formed. (The spindle is made of fibres which will eventually shorten to separate the chromatids.)...If you want to get a well(p) essay, order it on our website: Orderessay
