Ke ola kalapona o aeee - ka wā mai o kona hanau ana i ka kuokoa mahele paha make

Ke ola kalapona o aeee - i ka wā o ka haʻahaʻa ka mokuna o ka poʻe e ola ana, mai kona inception i kona mahele iho o ka papa a me ka make. Ka mea, nā mea a pau i ka loli maoli i undergo organelles e lawe mai kona hana.

Ke kaumaha ma muli kona hui a me ka specialization maʻamau aeea kalapona hiki mau i 30 minuke, a 3 lā. No ka laʻana, ka wā kaomi na keena ma echinoderms ke ola kalapona o 30 minuke, a intestinal epidermis ma kānaka - ma ka 12 hola. He nui no hoi ka poe walaʻauʻana huahelu o ke ola, i ua ole puunaueia, 'o ia hoʻi, mai paʻi, ka mea i hana i ko lakou manao hana, a make - .. ua like nā aʻalolo, striated Muscle olona. Pakiko aeea ola kalapona hiki ke maheleia i mau manawa: interphase, a me ka wā o ka ulu a me ka mitosis - wā mahele. Interphase nā, niioaaonoaaiii, he helu o nā kūlana:

1. G1 (postmitotic) - loiloi mua ulu pae. Ma kēia kahua, no kaʻaha kanaka o ke mRNA, nā polokina a me nā aeea eiiiiiaiou.
2. S (kemikala) - ia lŘlŘ DNA replication, e hiki aku ai i ka a pāpālua hoʻi o aaiaoe mea. I ka pauʻana o ka pae elua o ka ia palapala DNA pāpālua helix. Kēlā me kēia o nā kaula makalii o deoxyribonucleicʻakika maupaʻa kekahiʻoni iho kahiko, a me ka lua o ka - he hou kekahi, a i hana ma ke kulanui i nā kānaka complementarity.
3. G2 (premitotic) - o ke kapili kaʻina hana, i ka loaʻa o ? Iaea o ka wahaheʻe i loko o DNA hoʻololi kemikala i loko o ka mua pae. Loaa ka mahuaola, ikehu, hoʻomau i synthesize nā polokina, a RNA.

Ke kī hehee ai o ke kumu kāki i mitotic kalapona o aeea proliferative paha i hoʻomaka 'ana ma hope o G2. He He lākou no keʻano o ka hanaʻana i ana i loko o ke kula haʻahaʻa mall pa alima o ka noho ana, mai kekahi papa a hiki i ka kekahi welau, a hana i ka hou hanauna o ka hui ma lalo keena. Mitosis o ka papa kuhikuhiEʻano o somatic māhele (i komo i loko o ka moe nā'ōlelo) o kula haʻahaʻaa huahelu o nukelea meaola.

Ke ola kalapona o keena nui no ke kino, ina i ka maluhia o ka helu a me ke kinona o chromosomes ano o kela a me keia? Ueo (karyotype), no laila ia mea nui i nā mea a pau i ke ku e paha i hala me kekahi haunaele. Mitosis ua haku o 4 moekahi 'kūlana:

1. Prophase. Iloko o keia manawa, o ka halepaahao mahele ia lŘlŘ a me ka discrepancy ma waena o ka auamo centrioles, a i interconnected ma ka kālī mahele. Ma ka pau ana o keia wā nucleoli disintegrate chromosomeʻia naʻe, a hoopokole, a laila mea lākou condensation.
2. Metaphase. Nucleoprotein 'ole ua kūponoʻia ma ka equator aeee i hana metaphase una honua. Comes ka iniiaiie constriction o na chromosomes. A laila, kela mea keia mea o lakou, ua maheleia i mau chromatids.
3. Anaphase. Ma keia pae obrazovashiesya kaikamahine chromosomes neʻe i kekahi auamo, kahi a lakou i lalo mai, a unwind.
4. Telophase. Hoihoi hou ia i ka nucleolus, a me ka 'ōlelo mahele o ka cytoplasm ia lŘlŘ.

Penei, o ka halepaahao kalapona - i ka manawa o ke ola, mai ka hanau ana a hiki i ka haʻahaʻa pa alima o ka make ana o ka poʻe e ola ana.
