Replication - he a pāpālua hoʻi: hoʻokahi halepaahao, mai ka halepaahao

A pāpālua hoʻi i ke kahua o'ālike kope elua - ka kŰia kokoke maʻamau i loko o liluwelo nenoai. Pinepine ua kapaia keia a pāpālua hoʻi replication. Ka hope ke'ākoʻakoʻa ma kekahi pae o ka hui o ka mea - 'ana mai ka DNA i chromosomes a pau keena. I ka Ia manawa, ina ke kaʻina hele smoothly, loaa mau'ālike naehana. Replication - he a pāpālua hoʻi o kaʻikena Jewelry.

Pehea me kēia wahi

Ka oi hana hoihoi a me ke kumu no nā mea a pau'ē aʻe? Ueo ua manaoia i ka DNA replication. He He kaʻina hana ia i wahi ma luna o kekahi mau kahua o ka hoʻonaʻauao, kela mea keia mea o ka i pololei ka noho pilikia, no ka mea, o ka inaccuracy kāhea i ka hoʻololi kemikala o loa kūpono kumuʻiʻo uala pono no ka hoʻohana ma o ka halepaahao, a ma ka meaola like me ka a pau.

Ka wahi ho omaka

Replication hoʻomaka me aeea a pāpālua hoʻi DNA, a i kaʻilihune o ka a pāpālua hoʻi chromosomes. Akā, replication - o ke kihi o ka pau kaʻina. Ua ninoieo o ekolu kahua o ka hoʻonaʻauao. Mua, i ka hoʻomaka ai, ka lua, elongation, a me ke kolu, hoopau wale. Ka hana hoʻomaka me ka'ūhū noho pilikia nui - replicators a wale me ia. E hoomaka ana ma ka hewa wahi e paha ka nānaina i ka pau kaʻina. Ke'ūhū-hōʻeleu haʻalele no ho'ākāka nā polokina mea nāna i hana i ka mālama '-replication eiiieaena koi' ia no ka DNA a pāpālua hoʻi. Ma mua o ka multiplication o DNA ua oki i loko o nā māhele ma kekahi nā'ūhū.

Ka mea manuahi kaula

I ka wā o ka elongation ma ka'ōpū mai kūkulu mea manuahi makua kaula. Ia mea, hoʻokahi i laila hana hiki i ka piha lātoma. Ke kaʻina welau a me ka hoopau i kekahi i loko o ia lŘlŘ ka kekahi wahi. Aia He He kūikawā pa alima - ka replicon. 'O kēia ka DNA apana nahaha e kükulu i ma manawa. DNA replication - ke kumu, me ka mea hiki ole ke replicated chromosomes. Ka hope ia lŘlŘ ka wā o ka halepaahao prepares e puunaue.

Kumuʻiʻo like me ka hōʻailona

Ua hoʻomaka chromosome a pāpālua hoʻi i loko o kekahi mau hola ma hope o ka mea i hiki mai ai DNA a pāpālua hoʻi. E kūkulu hou i ka chromosome, ua pono ole wale hou e puhi ia o deoxyribonucleicʻakika, akā, i nā polokina i kekahi hapa o ka chromosome i hoʻomākaukauʻia, a me kā lākou hoʻololi kemikala pono manawa. Fast replication - he hoailona o ka maʻi 'aʻai. Inā ka mea, huai ae nui loa kumuʻiʻo, ano no, pili ke kelepona hele mahele, ke kauka hoʻomaka e hoʻokani i ka pū waikaua.

makahiki lawa

Aia nō i loko o ke kaʻina hana o ka replication mea he nui hiʻona - ma ka Kernel makahiki ma ka hua'ōlelo o ka hoʻololi kemikala o hou DNA i ke 'ano kōā kaulike, no laila, he mea ole ei, a hiki hoʻonāukiuki i ae ole. Muli o kona kulana i ka puu o ke kumu, IeAUPIIe, IAa IO he hapalua i mau kakini.

Pehea kēia nui e e hoʻonohonoho chromosomes mea hilinaʻi nui i hanaia i loko o ka halepaahao mitosis paha meiosis. Ma ka hihia mua, i ke kūpono aeea makemake ia i ka mau kau, i loko o ka lua - hapalua. Ma hope o nā mea a pau, i ka kekahi hapalua, e lawe mai i ka halepaahao o ka lua o ka hoa i loko o ka 'īnea i nā'ōlelo. Inā ma ka meiosis koke kiʻi i ka piha kau, gamete paha e unsustainable, paha e ka hapai ana o ka maʻi keiki. Eia naʻe, i kēia mau keiki nō i oi ma mua,ʻaʻole pinepine hanau, aia no he miscarriage i loko o kakahiaka hāpai keiki, i ka makuwahine, ka poe hiki ke lawe ma luna o ka malama ovulation paha kahe ana ke koko ma ka waena o ka pōʻaiapuni.
