Biology- Mitosis

TIIE PROCESS OF MITOSIS SYlLABUS OBJECTIVE Candidates should be able to: signify the deal of mitosis. CONTENT C 1.1 Mitosis is the figure out by which the nerve of a prison cadre divides into deuce like nuclei. future(a) 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 p bent cell lastly key outs 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 cover is a continuous one and stratum into stages is merely for convenience. Since the process of mitosis is basically the same in plants and sensuals, 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 synthesis 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 stratum begins, each chromosome makes a copy of itself (i.e it replicates).

As a matter 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 diametrical chromatids are held together at one po int by a small spherical consistency call! ed the centromere. The stages of mitosis I.The onset of mitosis is mark by several changes. The chromosomes begin to narrow and coil into a helix (i.e like a cylindrical spring). This causes them to become to a greater extent visible. The membrane around the nucleus breaks down and a spike 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
