Baai ni Nalawa, nalawa iparipi al kopuna baai baai al kopuna baai baai. Baai ni Nalawa, nalawi iparipi al kopuna baai baai al kopuna baai baai. Teneqa il shanirdoum thou ma denin paringshi shah put put shingyadow, mush porutu denimwaydus indelu ho alink shushyana. Baii ni Nalawa, nalawa iparipi al kopuna baai baai(sasawah, puoltuk) al kopuna baai baai. Kalaam saah kalaam saah aladiji paradi lin, daja asajah kun sawah. Tell me have you ever heard the place in the united land, well heres a chance to prove to all we can build this land. Hey baai ni you heard them say it out loud it means the land is great so we gotta work now we gotta come together, bind together, do everything possible just to be together. Before the discovery of cell division there were many theories on how the cells are related to the overall development of an organism’s lifecycle.Aai ni Nalawa, nalawa iparipi al kopuna baai baai al kopuna baai baai. One of which was Rudalph Virchow’s theory of cell: “Omnis cellula e cellula” which states that a cell originates from a pre-existing cell. Walther Flemming discovered and published a detailed book on cell division in 1882 after discovering cell division in 1879. He named it “Mitosis” after the Greek word Mito – “Wrapping thread” owing to the thread like appearances of the chromosomes. He conducted a detailed study and deduced staining techniques to understand cell cycle and named the stages of each division as Prophase, metaphase, Anaphase and Telophase. The cell division was identified in Salamander’s embryo. Flemming supported Virchow’s cell theory with precision and stated that “Omnis nucleus e nucleo” which states that a nucleus origin from a pre – existing nucleus and highlighting the chromosomal segregation and laid foundation for the theory of inheritance where the chromosomes play an important role carrying the genetic information from the parent to the offspring.Ĭell must completely prepare for the cell division to support it. This is done by Nucleolus disintegration: condensation of the chromosomes restricts the site for gene expression which is essential for the cell coordination and synchronization. When the region is coiled in the chromosome regular functions cease to exist thereby releasing inhibition from the nuclear membrane for CDK’s to phosphorylate the nuclear inner lamina which disintegrates into small protein speckles similar to that of ribosomes. ![]() The condensation restricts the transcription of the cell maintenance this may lead to the disintegration of nucleolus and nuclear envelope. The disintegrated envelope is further displaced by Microtubules with an influx of Ca and Protein Kinase C. The spindle formed were present form the S phase which are also eliminated and new Microtubules are formed. Primary Constriction in the same chromosome results in the formation of a chromosomal element – centromere plays an important role in connecting spindle fibers for the chromosomal segregation. Main changes in the cell cytoplasm are: the reduced protein synthesis by a mechanism which is to be deduced. Micro tubulars and Microfilaments from interphase disintegrate and new ones are formed, additionally the region of cytokinesis is marked in the cell cortex by the thick actin bands – Preprophase Bands. “Tog” domain proteins initiate the microtubular formation by catalyzing the polymerization of tubulin. ![]() The mitotic restructure is essential to govern the cell at structural level. In mitosis the cytoplasm remains immotile due to absence of the microtubules and microfilaments of the cell causes notable changes to support the divisionġ. ![]() New microtubules are synthesized which will support the cell cycle of the daughter cells.Ģ. ![]()
