Kedu ihe bụ ebumnuche mitosis?
Sel bụ akụkụ arụ ọrụ nke na -akwagharị ọrụ ndu nke ihe niile sitere na nje na fungi ruo whales na -acha anụnụ anụnụ na nnukwu osisi uhie. Ihe owuwu ndị a siri ike, dị mgbagwoju anya, mana nke na -adịghị ahụ anya na -enweta uto na mweghachi nke ihe ndị nwere ọtụtụ mkpụrụ ndụ site na mitosis, usoro dị ịrịba ama nke na -agbanwe sel ka ọ bụrụ sel abụọ.
Nkọwa ziri ezi
Ihe bụ isi nzube nke mitosis dabere na pụtara itinye n'ọrụ n'okwu a. A na -atụlekarị mitosis dị ka otu okwu maka nkewa sel. N'okwu a, mitosis bụ usoro nke otu selụ na -esi emepụtaba onwe ya wee mepụta sel nwa nwanyị.
Nkọwa ọfụma nke ziri ezi nke mitosis bụ usoro nke nucleus na -emepụtaghachi onwe ya wee kewaa onwe ya ụzọ abụọ nke nwere ezigbo mkpụrụ ndụ ihe nketa.
Isi ọhụrụ
Mitosis, dị ka nkọwa a kapịrị ọnụ si dị, nwere akụkụ anọ bụ isi: prophase, metaphase, anaphase, na telophase. Akụkụ atọ nke mbụ na -emetụtakarị nkewa na nhazi nke chromosomes nke emegharịrị n'oge interphase, nke bu ụzọ mitosis.
Chromosomes bụ mkpụrụ ndụ ogologo nke nwere ozi mkpụrụ ndụ ihe nketa n'ụdị deoxyribonucleic acid, nke a na -akpọkarị DNA.
N'oge telophase , nucleus ọhụrụ na -etolite gburugburu kromosom ọ bụla, na -ebute nuclei nke yiri mkpụrụ ndụ ihe nketa. Mitosis na -ebu ụzọ na usoro nkewa sel n'ihi na selị ọhụrụ enweghị ike ịdị ndụ na -enweghị isi nke nwere ozi mkpụrụ ndụ ihe nke dị mkpa maka njikwa ọrụ cellular.
Otu selụ, selụ abụọ
Nkewa selụ na -amalite site na mitosis wee kwụsị ya na cytokinesis, ebe mmiri selụ, nke akpọrọ cytoplasm, na -ekewa wee mepụta sel abụọ n'akụkụ okirikiri abụọ etolite n'oge mitosis.
N'ime sel anụmanụ, cytokinesis na-ewere ọnọdụ dị ka usoro wara wara nke na-emesịa tinye mkpụrụ ndụ naanị nne ma ọ bụ nna n'ime ụzọ abụọ. N'ime mkpụrụ ndụ ihe ọkụkụ, cytokinesis na-arụ ọrụ site na efere cellular nke etinyere n'etiti selụ ma kewaa ya n'ime sel abụọ.
Enweghị Nucleus, enweghị mitosis
Nkọwa nkenke nke mitosis dị ka nkewa nuklia karịa nkewa selụ na -enyere aka dokwuo anya otu ihe dị mkpa - mitosis na -emetụta naanị sel eukaryotic. Mkpụrụ ndụ niile na -adaba n'ụdị abụọ sara mbara: prokaryotic na eukaryotic. Nje bacteria na otu ihe e kere eke nwere akpọrọ archaea bụ sel prokaryotic, na ihe dị ndụ dịka osisi, anụmanụ na fungi nwere sel eukaryotic.
Otu n'ime ihe na -ekpebi ọdịiche dị n'etiti ụdị sel abụọ a na ọnụnọ nke isi: sel eukaryotic nwere isi dị iche, yana sel prokaryotic enweghị. N'ihi nke a, mitosis enweghị ike itinye aka na nkewa sel prokaryotic, nke a na -akpọ ya nkewa ọnụọgụ abụọ.
