Ke liluwelo manaʻo nui o ka mitosis

Ke liluwelo manaʻo nui o ka mitosis ka loa kiʻekiʻe. Neposveschennomu a hiki paakiki e noonoo ai i na i ke kūlana hoʻokani i loko o ke ola ana o ka poe noonoo ole kaʻina hana o ka halepaahao mahele i loko o ke kino. I ka hiki ana o aeee e kaʻana - keia mea no ka nui loa o ko lākou mau papa, i ka nń ku. Me keia mea, he mea hiki ole ka hoomau ana i ke ola ma ka Honua, mahuahua ka heluna kanaka o ka hookahi-aa? Meaola hiki ole ulu, a me ka hoʻomau ola o ka nui multicellular meaola, he mea hiki ole like moe nā'ōlelo ma ka hooulu ana o ka hou ola ana, a no ka fertilized Kepakailiula.

Ke liluwelo manaʻo nui o ka mitosis makemake e nui emi ina ka halepaahao mahele ua i ka pā like o ka hapanui e lawe wahi ma luna o mākou Honua liluwelo keʻano o ka hanaʻana. Kēia kaʻina hana i wahi i loko o kekahi mau kahua o ka hoʻonaʻauao. Kēlā me kēia no ia mai nā 'kekahi mau hana i loko o ka halepaahao. I ka hopena o keia mea OAXA multiplication o ka aaiaoe muli o ka hookahi aeea ma ka hapalua ma ka a pāpālua hoʻi DNA e a laila i hanau i ka makua aeea i mau kaikamahine.

Ke holoʻokoʻa ola o ka halepaahao hiki e manao ai ma ka manawa, mai ke kahua mai o kekahi hui ma lalo a hiki i kona mahope mahele i loko o elua. Kēia manawa i loko o kālaimeaola i kapa ia "aeea kalapona".

Ka loa mua pae o ka mitosis - he kupono makaukau no ke kelepona hele mahele. Manawa ma a na aeee i kuʻu maiʻanoʻano,ʻaʻole hana pololei makaukau no ka mahele, i kapa interphase. Ua ka hana a pau na mea nui - oia, i ka a pāpālua hoʻi o ka DNA kaula makalii, a me na hale, e like me ka hoʻololi kemikala o ka nui dala o ke kumuʻiʻo. Penei, i papalua o ka halepaahao chromosomes, a ua kapaʻia kēlā me kēia hapalua o ka papalua chromosome "chromatid".

Ma hope o interphase hoʻomaka 'ana i ke kaʻina hana o ka papa - mitosis. He, hoi, e kaili ia wahi i loko o kekahi mau kahua o ka hoʻonaʻauao. E like me ka hopena, a pau o ka pāpālua hohola symmetrically i loko o ka hīnaʻi manu, no laila ia ma hope o ka ho okumu ana o ke kikowaena paku i loko o kēlā hou aeea i hana i ka mea helu o eiiiiiaiou i koe.

Nā kūlana o ka mitosis a me ka meiosis mea like, akā, ma ka la mahope (ma ka mahele ana i germ aeee) he māhele elua, a ma ka hopena e huli mai i elua, akā, eha kletki "kaikamahine." Nō hoʻi, ma mua o ka lua o ka mahele kahi waiho chromosome a pāpālua hoʻi, no laila, e waiho ana no kā lākou hapalua kauʻia i loko o ke kaikamahine keena.

1. Prophase. Ma keia pae, aeee centrioles i loa hiki. Ka mea, i kēia manawa wale nō i loko o ka halepaahao o ka holoholona a me nā kānaka. Nā mea kanu aʻole 'oe i centrioles.
2. prometaphase. Ma keia wahi e na welau prophase a me ka metaphase huli no.
3. Metaphase. Ma kēia wahi, i nā chromosomes moe ana ma ka "(Equator)" o ka halepaahao.
4. Anaphase. Chromosomes e hele aku i kekahi mau auamo.
5. Telophase. Kekahi aeea-ka "makuahine" Ua puunaueia ma ke kahua o ke kikowaena paku i loko o nā kletki "kaikamahine." Ke'ī mai ke hoʻoholo 'ia i ka halepaahao mahele paha mitosis.

Ka loa nui liluwelo manaʻo nui o ka mitosis - Ua like ka hookahi mahele o na chromosomesʻia i kekahi i loko o 2 like māhele a me ka haawi ia lakou i loko o nā kletki "kaikamahine." ʻano o aeee a me na keena o nā meaola i ka lōʻihi like HEN manawa mahele - mitosis, akā, ma luna o kaʻawelike ia ai ma kahi o kekahi, a me ka hapalua hola. He nui aʻe i ho ololi i keia loa fragile kaʻina. Kekahi hoʻololi? Aneie rula, e laʻa me, Ambient mahana, malamalama pae 'ano, i ka puʻe i loko o ka' āina, a ma ka meaola a me aeee e like me na mea he nui 'ē aʻe paha me ka nui loa pili nā ka lōʻihi like' ole, a me ka pono o ke kaʻina hana o ka halepaahao mahele. Nō hoʻi, i ka lōʻihi like 'ole o ka mitosis, a pau kona kanaka kahua o ka hoʻonaʻauao hiki e pololei kalele iho ma luna o ka'aʻaʻaʻano, ma aeee ana i puka mai.

Ke liluwelo manaʻo nui o ka mitosis me kēlā hou loaʻa i loko o ke kula o ka cytology i oi waiwai, no ka mea, me ka hiki ole i kēia kaʻina hana e ola ma luna o ka Honua.
