Biology- Mitosis

TIIE PROCESS OF MITOSIS SYlLABUS OBJECTIVE Candidates should be able to: advert the deal of mitosis. CONTENT C 1.1 Mitosis is the bear upon by which the perfume of a prison cadre divides into ii like nuclei. next this, on that point is separation of the cytoplasm into two cellular ph bingles each containing a nucleus. During mitosis the chromosomes of the dividing cell behave in a specific way. This pargonnt cell lastly elucidates into two identical cells called girl cells. distributively daughter cell contains the analogous number and types of chromosomes as the parent cell. It should be noted that the bring is a continuous one and stratum into stages is merely for convenience. Since the process of mitosis is basically the same in plants and animate beings, the process in animal cells will 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 discount and other processes related to its special roJe in the life of the tissues or organs of which it forms a part. Just forwards cell naval division begins, each chromosome makes a copy of itself (i.e it replicates).

As a final result of this process, each is now composed of a pair of structures, called chromatids. Each chromatid is a complete chromosome containing information identical [0 that of the original chromosome. The diametric c hromatids are held together at one point by ! a small spherical consistency called the centromere. The stages of mitosis I.The onset of mitosis is attach 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(prenominal) visible. The membrane around the nucleus breaks down and a mandrel 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: BestEssayCheap.com
