Like hou aeee i hanaʻia ma mitosis: hiʻona a kaʻina waiwai

Kekahi o na kumu o ke kaulana halepaahao pähola 'ana o ka' ole o kekahi māmala'ōlelo e pili ana i keʻano o ka hou keena, mai ke kumu, oa i ka makua. Akā, ka mea hiki ke hana ia ma nāʻaoʻao. Kekahi o ia mea mitosis. He mea nui i ke kaʻina hana o ka'ōlelo o ko lākou mau ano. A aeee i hanaʻia ma mitosis, ka mea i ko lakou helu a me nā 'ano o ke kaʻina hana - a pau keia e e kūkākūkā i au mamuli o keia Haawina.

aeea kalapona

Ke aeea o kekahi meaola hiki ia o na loko o ka nahā i waena o nā o kona hoea ole mai o ka hoomaka ana o ke kaʻina hana i hiki i ka manawa o ka make. Kēia koe i ka manawa, a me ka halepaahao kalapona. Ua maupaʻa na kapuai o ka mahele kaʻina a me kekahi manawa wā mawaena ma waena o lākou, i kapaia o interphase. Ma keia manawa i ka halepaahao ka ulu ana a me ke kahua o ka māhuaola.

Akā, i kekahi o na mea nui a pau o ke kaʻina hana o ka a pāpālua hoʻi DNA macromolecules. Aia ua hoʻopā'āluaʻia a pau o ka aaiaoe ike o ka halepaahao.

Pehea ka aeea mahele

Me ka meiosis hoʻomāhuahua sperm a me ka ovum. Ke ae pā o kēia kaʻina hana o ke kahua o ka eha haploid gametes mai ka makuahine aeea me ka papalua kau o chromosomes. No keia kumu ka mea, ua kapaʻia meiosis. He mea nui no i fertilization o ke keka keena, he hou kino, na ka hapalua o ka aaiaoe ike ana o ka makuahine, a me ka makuakane. A me keia mea hiki ma lalo o ke ana ana i ka gametes i haploid wale.

A aeee i hanaʻia ma mitosis? Ka poe noonoo ole pane Ua diploid, i mea, me ka papalua chromosome huapalapala. Kēia kaʻina Ua hoi nui. Ka mea Ua e like me ka hopena o ka mitosis hua aeee i mea he kope mau o ka makua. i somatic a pau o ia mau mea.

Nā kūlana o ka mitosis

Ke kaʻina hana o ka ho okumu i hou somatic aeea kikowaena mau kūlana. Lākou nohona ma lōʻihi, ke kaumaha ma muli o ka laha 'o ka meaola loli aʻe mai kekahi mau minuke i kekahi mau hola.

Ka loiloi mua ke kahua me ua kapaia prophase. I keia manawa he mea he pae o ka chromatin compaction, ka ho'ēmiʻana o nucleoli, mitotic kālī ho okumu. disintegrates kāna mau 'ōlelo iwi ma muli o chromosomes hāʻule i loko o ka cytoplasm.

Ka lua o ke kahua ua kapaia ka metaphase. Kona o Mānoa, ke moe i loko o ka hana ana o na chromosomes i loko o ka hookahi pelane, a me ka hoʻopili ia kālī pae. Kēia Ua ukali ma anaphase, i mea ka loa pōkole-noho pae. E like me ka hopena o ka mitosis hua maopopo i hana kaikamahine keena. Kēia kaʻina welau i ka anu u telophase. Ma ka Ia chromosome dispiralized. Ka mea, ua kokoke e hiki ma lalo o ka malamalama microscope. Next, e pili ana i chromatids hoʻomaka e hana i kāna mau 'ōlelo iwi a me ka mahele ana i kālī nalo i nā.

Ehia na aeee i hanaʻia ma ka mitosis

Mitosis like me ka ano o ka mahele o ka eukaryotic keena o ka loa, he pono ole ma ke ano. Loaa o ka nalowale a poino māhele o ke kino o kaʻoi loa no ka mea, o keia kaʻina. E like me ka hopena o ka mitosis mau kaikamahine aeee i hana mai i ka hoʻokahi makua. I ka Ia manawa, ku pono i ka a pāpālua hoʻi o ka DNA nā lātoma i loko o ka interphase o ka halepaahao kalapona, ma laila e waiho ana no he diploid chromosome huapalapala.

Mitosis - i ke kumu o nā mea a pau ano o asexual nā'ōlelo: vegetative - i ka mea kanu, aeea mahele i loko o nā māhele - ka simplest, nunui-mahae - ka malaria parasite, spore - fungi a me Fern, i opuu ae - coelenterates.

Ke liluwelo manaʻo nui o ka mitosis

Ke keena i hanaʻia ma mitosis me ia chromosome i like me ka makua. E like me ka hopena i ka kaʻina hana o laila 'o ia aaiaoe' ike, i mea nani wale ka nui paʻa mahele o kekahi hooko mai. I loko o kēia kaʻina hana i koe a eia i, a me ka helu o nā chromosomes, a me ke kaʻina o nā nucleotides ma ka DNA nā lātoma.

Penei, e like me ka hopena o ka mitosis mai ka hookahi aeea hana mau kaikamahine i hoopau ai i ke replicate i ka mua. Kēia e hōʻoiaʻiʻo i ke kumupaʻa o karyotypes a mea he elue no ke ola ana o nā mea a pau meaola e noho ana mawaena o ka wā o ko lākou mau kanaka, a me ka mōʻaukala? Acaeoey.
