Ke mitotic kalapona ano o ka keia kaʻina

Mahele - he waiwai nui o ke keena. Me keia kaʻina, he mea hiki ole ke manao wale ka hua i loko o ka helu ana o kekahi anakahi iki-meaola a unicellular mea. Eia hou, ka mea e hōʻoiaʻiʻo i ka loaa ana o nā'aʻaʻa a hiki holoʻokoʻa nā loko o multicellular meaola.

It E e hoʻomaopopo i ka i ana i keʻano o ka hanaʻana i lawe wahi i loko o ka wā ma waena o nā papaʻelua, i kapaʻia ka halepaahao kalapona. Ua lawe wahi i loko o kahua o ka hoʻonaʻauao. Ke'ī mai, i ka pono ano o ka interphase a mitotic kalapona ma i ka halepaahao i hookaawale ai.

No ka malama ana i kūpono dala o aaiaoe mea hele a pāpālua hoʻi DNA nā lātoma. Eia hou, i ka mau 'ae i ka biosynthesis o nā polokina, a me nā kahua o ka nui aeea hale.

Au pono aku nei au i ka interphase hou ma mua o ka mahele iho. Ua ninoieo o na kēia mau kapuwai.

• presynthetic wā - Ua wehewehe aku ma kaʻeleu ulu keʻano o ka hanaʻana, me ka hoʻololi kemikala o nā polokina, a nukelea nāʻakika, a me ke kahua o ka hana i ho'ākāka 'activators kemikala wā. kona maʻamau nui ka halepaahao kīnā a me ka hooponopono i pono ai no ka functioning o ka organelle. Ka lōʻihi like 'ole o kēia wā - he mau hola paha lā.

• kemikala wā - wehewehe aku DNA replication a me ka hoʻololi kemikala o histones, i nā kuleana no nucleosome'ōpala o ka lānai hou synthesized nukelea nāʻakika, e like me ka a pāpālua hoʻi o nā chromosomes a me centrioles. Ka lōʻihi like 'ole o kēia wā - mai i ka 12 hola.

• postsynthetic wā - mau a mitosis, wehewehe aku ma ka hoʻomāhuahua o ka ikaika a me ka kumuʻiʻo hoʻololi kemikala o tubulin, i mea nui no ka aeea mahele. Pau i ka wā o ka 2-4 hola.

A ma hope iho hele mitosis interphaseʻanuʻu, a ua i wehewehe aku e kekahi ka mea i hahai ana ka mea mamuli o kekahi keʻano o ka hanaʻana i loko o i ke kaikamahine aeee i hana i ka pono-i ho'ākāka 'ia paha o nā chromosomes.

Ua mea waiwai 'ana i kumumanaʻo ia a hiki i kēia lā kona mau helehelena kumu no ka hoopau ana i ka fission kaʻina. Ua meaʻikeʻole, a me nāʻano papa hana e triggers kona resumption, eia nae kaa hormones a ma ka hana ana o ka mitotic kalapona ua ho'ā '. Nā kumumea ke kaōhiʻana i ka nui o ka heluna kanaka o ke keena, no hoi i maopopo hoomaopopo.

Ma ka mitotic halepaahao kalapona ua 'ole ma glucocorticoids. Prolactin, thyrotropin, estrogens a me androgens mea i hiki no i kekahi ala ololi i ka mahele o ke keena i loko o ka pale umauma hoʻokahi nā'aʻaʻa.

He waiwai 'ana i kumumanaʻo ka kēia mau hiʻona benign hikoko - no ko lakou ano circadian mitotic aeea kalapona (kela la i keia). Ua Ua manaoio aku i ka wā iʻeho Holomua ia lŘlŘ he emi ma ka pā lonoaʻili o ka meaola i R. N. chalones - keena nā mea kūpale.

Ma ka mahele a me ka nui o ka halepaahao lehulehu ua i 'ole ma o ka ha awina o ka lysosomal'ōnaehana, no ka mea, kona nā'ūhū hiki e luku ai.

Ua pono e mai la oia i ke kahua o ka hou aeee mea e kaukaʻi ma ke 'ano o ka'aʻaʻa, i ka aoao o ka mawaho aʻe, a me ka physiological moku'āina o ke kino, no laila, i loko o kekahi mau hihia ka mea, ke i kekahi kanaka ano, wehewehe aku ma ka hou ulu o ka halepaahao lehulehu a me ka hoopau ana o ke kaʻina hana.
