Kamere izi uburyo bwo gukomeza uburinganire. Aya magambo nukuri kandi ajyanye nibimera agaburira ibyatsi - Udukoko cyangwa inyamaswa z'inyamabere.
Muri icyo gihe, ibimera ntibyemera bucece kwiyese. Mubyukuri, bateguye gahunda yo kurinda ibabuza ibitero byangiza inyamanswa kandi birashoboka ndetse no kwerekana ibitero.
Sisitemu yo kurinda ibaho nkibisubizo byimbere nuburinganire bwo hanze.
Ibimera byateje imbere inzira nyinshi zo kumenya ibyangiritse; Benshi muribo bahujwe n'imyumvire ya molekile zitandukanye zakozwe na prestator cyangwa ibimera ubwabo, kandi batangira ubwoko bwa "SOS ikimenyetso".
Mu kiganiro gishya cyatangajwe mu kinyamakuru kinyuranye na Science Science, Porofeseri Ichiro Arimura wo muri kaminuza ya Tokiyo ya Siporo ya Tokiyo ya Siporo ya Leta, Ubuyapani bwanditse ku byerekeye ibinyabuzima. Niki?
Iyo herbivore imwe ije kurya inshuro nyinshi, igihingwa kiga kumenya urunigi rw'ibitekerezo kandi "karagaragaza" igishushanyo kijyanye na moleki "kijyanye nacyo. Ibi byitwa "inzego za molekile zijyanye ninyamaswa za herbivale" cyangwa hamp. Hamp ni elixzers yavunitse.
ibimera n'ibindi elixitors harimo ibikomoka ku bimera bahari imbere utugari ko seep inyuma kubera ibyangijwe mu kugaburira.
Igishimishije, iyo udukoko twa hebivore arya igihingwa, ibicuruzwa byo gusya inkuta z'ibimera na selile zigize selile ziba mu ibanga ryo mu kanwa (OS) z'igituba, zishobora no gukora nk'iryisi.
Porofeseri Arimura ashimangira ko hamwe nuburyo bwo guteza imbere uburyo bwo murwego rwohejuru bwo kumenya ingirabuzimafatizo na poroteyine, biranga indabyo zimwe na hamwe, nubwoko bwumutobe wa selire kandi udatanga OS, byashobokaga.
Poroteyine ziboneka muri glande yitabi yinyuka nkizo zirashobora kuba elexizers, uko zigwa mu gihingwa mugihe cyo kugaburira.
Asigura ati: "Isesengura rya RNA na Proteoma ryerekana amacandwe yo konsa yemereye kuranga poroteyine nyinshi. Muri Proteleine ya Mucinoodebide igihingwa mu gihe cyo kugaburira. "
Iyi ngingo kandi itandukanya elitiners yihariye nkamagi nudukoko twihariye. Ibimera birashobora gutahura no gutuma reas zikingira. Mubibazo byihariye, bagiteri ya symbiotic ituye mumahanga udukoko arashobora kandi gukora sisitemu zikingira.
Noneho, iyo dukemuye ubwoko butandukanye bwabato, ikibazo gisigaye - ni ubuhe buryo bwa kimenyetso ukoresha ibihingwa kugirango wohereze ibimenyetso bya SOS?
Hypothesis yari agishyikirijwe ko kohereza ibimenyetso bishoboka kubera poroteyine zitwarwa nigitambaro cyibimera.
Muri icyo gihe, hari ibimenyetso byerekana "ikirere cyo kumenyesha ikirere". Ibimera birinda mugihe cyangiritse kumiti ihindagurika ishobora kubonwa nibimera byegeranye.
Hariho kandi ibimenyetso byamabwiriza yo muri epigenetic mugihe ibimera bishyigikira ubwoko bwa "genetike yibumoso" yudukoko twangiza kandi birashobora kugena neza igisubizo kikirinda kubitero bizaza kubitero biririndwa.
Urebye imbere ubumenyi kubyerekeranye nuburyo bwo kurinda ibihingwa, dushobora kwemeza uburyo bwa "genetique" yo kugenzura udukoko. Uburyo nk'ubwo bwo kugabanya cyangwa kureka imiti yica udukoko twa imiti na gato, bigatera ibirego byinshi kandi bishingiye ku miryango ya gitsina. Byashoboraga gufungura uburyo bugezweho, bushingiye bwa siyansi bwo guhinga imbibi, bityo bukemuye ubuhinzi-umwuga wo kwishingikiriza udukoko twitwaje imiti yica udukoko.
