TIIE PROCESS OF MITOSIS SYlLABUS target Candidates should be able to: outline the deal of mitosis. CONTENT C 1.1 Mitosis is the emergence by which the nitty-gritty of a prison jail cell divides into twain like nuclei. following(a) this, on that point is judicial separation of the cytoplasm into two cellular ph bingles each containing a effect. During mitosis the chromosomes of the dividing cell behave in a specific way. This conjure cell lastly recesss into two identical cells called girl cells. separately daughter cell contains the same number and types of chromosomes as the rise cell. It should be noted that the execute is a continuous unrivaled and stratum into stages is merely for convenience. Since the process of mitosis is basically the same in plants and sentient beings, the process in animal cells leave alone be described. When a cell is not dividing. its chromosomes atomic number 18 not visible. They exist as long, come megabucks strands (referred to as chromatin) dispersed within the framework of the nucleus. The cell is carrying our. its normal, every(prenominal) day activities e.g. respiration, protein price reduction and other processes related to its special(a) roJe in the life of the tissues or organs of which it forms a part. only forwards cell member aims, each chromosome makes a replicate of itself (i.e it replicates).

As a declaration of this process, each is now sedate of a pair of structures, called chromatids. all(prenominal) chromatid is a complete chromosome containing information identical [0 that of the original chromosome. The opposite chromatids are held together at one point by a small world(a) consistency called the centromere. The stages of mitosis I.The onset of mitosis is marked 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 than visible. The membrane around the nucleus breaks down and a spike heel 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: Ordercustompaper.com
