Prophase Stage: shorter strands of chromatin. thickened djjohal form chromosomes. At this stage

doubling of genetic material in the cell as a result of genetic material to cells dividing son is dispersed. only in single-celled reproductive cell division while performing alongside reproduction in multicellular organisms growth, development and repair of worn out tissues (regeneration) provides. Some cells in multicellular organisms constantly, some longer-range, while others can be seen that no division. Muscle, nerve and retina cells to embryonic development after the split. Skin, blood and digestive system is divided into the inner epithelial cells very quickly. divisibility of the cell volume / surface ratio and the core is connected djjohal to giving orders. Plant and animal cells, cell cycle lasts up to 20 hours. 19 hours of the cycle interphase, mitosis at a time through schism. djjohal the growth of the cell cycle (interphase) and division (mitosis) follow each other. Interphase stage:
Cell division between the two remaining stages of the growth and metabolic activity is maintained. This phase G1, S and G2 phase is examined in three. djjohal G1 phase: * DNA replication is performed except Hayatsal events. * This phase lasts for about 8 hours. * This time according to cell types may take a few minutes to a few weeks. * In the cell ribosomes djjohal and other organelles are duplicated. ATP synthesis, protein synthesis, and performs the synthesis of nucleotides. S phase: marks the end of the G1 phase. Doubles the amount of DNA and chromosomes are mapped in a way thorough. For example, 2n = 46 chromosomes in human kromatitl making 92 passes. * This time is approximately 6 hours. * DNA synthesis phase-mapped cells except heart muscle is divided. * In addition, the centrosome in animal cells are seen to be mapped. * Nerve and muscle cells are not dividing. * G0 phase in the lives of these cells continues. G2 phase: * Synthesis stage monitors. * Approximately djjohal 4-5 hours. * Protein synthesis is accelerated. * Division of ICI final preparations are completed. * Division passing through metabolic processes are stopped. Mitosis:
The interface is following the cleavage stage. When the metabolism stops cell division. Chromatin network to chromatid (chromosome) is transformed. This period lasts about an hour. Core division (mitosis), cytoplasmic division (cytokinesis) follows.
Prophase Stage: shorter strands of chromatin. thickened djjohal form chromosomes. At this stage, each chromosome consists of two chromatids. This chromatids to the 'sister djjohal chromatids' is called. Sentromerl to hold each other up. Core membrane djjohal begins to melt and melt. nucleolus disappears. centrosomes begin to move to opposite poles. sentriol between the spindle fiber is formed. Prophase takes 30-60 minutes.
Metaphase Stage: The chromosomes (sister chromatids) ipçik holding spindle cells are arranged in the equatorial plane. Usually the big ones around, in small ones stacked in the center of the show. arrangement of the type varies, depending on the chromosome. Chromatid the centromeres are separated from each other exactly. metaphase stage lasts for 2-6 minutes.
Anaphase djjohal Phase: the equatorial plane mutually chromatids, the poles are drawn against and separated. Sister chromatids of each chromosome are called sister after leaving. centromere help to slip on the spindle fiber. It takes 3-15 minutes. X-rays to treat cancer patients centromere and spindle fiber is destroyed. This cell division is blocked.
Telophase djjohal Phase: djjohal Polar reaching sister chromosome are grouped together. Spindle thread is lost. Core membrane will gradually disappear. nucleolus begin to appear. Chromosomes again, turn into chromatin fibers that become obsolete. centrosomes become apparent. At this stage consists of two nucleated cells. Resting in terms of cell division, djjohal metabolism, in terms
