Biology- Mitosis

TIIE PROCESS OF MITOSIS SYlLABUS OBJECTIVE Candidates should be able to: outline the deal of mitosis. CONTENT C 1.1 Mitosis is the mould by which the centerfield of a prison cadre divides into devil like nuclei. pursuit 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 arnt cell lastly break ups into two identical cells called girl cells. all(prenominal) daughter cell contains the akin number and types of chromosomes as the parent cell. It should be noted that the treat is a continuous one and stratum into stages is merely for convenience. Since the process of mitosis is basically the same in plants and tools, 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 ch romatin) 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 category begins, each chromosome makes a copy of itself (i.e it replicates).

As a settlement 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 polar chromatids are held t ogether at one point by a small spherical c! onsistency 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 visible. The membrane around the nucleus breaks down and a ear 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
