Eukaryotic cell da tsarin da kuma aikin kungiyar

eukaryotic cell ilimi shi ne na biyu a muhimmanci (bayan bayyanar rayuwa kanta) wani juyin taron. Babban kuma bambancin na eukaryotes daga prokaryotes ne kasancewar wani karin cikakken tsarin na genome. Godiya zuwa fitowan da kuma ci gaban da wani cell tsakiya, sharply ya karu mataki na adaptability na unicellular kwayoyin zuwa a kai a kai canza yanayi da kuma ikon daidaita da sauri ba tare da yin wani gwaji canje-canje ga hereditary kwayoyin tsarin.

Eukaryotic cell, da cytoplasm na wanda shi ne wani yanki na aiki tafiyar matakai na rayuwa, da kyau a rabu da ajiya yankin, da karanta da kwafi na kayyade bayani, ya iya karfafa nazarin halittu juyin halitta. Wannan shi ne wani alamar da muhimmanci juyin taron, bisa ga masana kimiyya, ya faru ba daga baya fiye da 2.6 biliyan shekaru da suka wuce, a yankunan na biyu ma'aunan kasa da waɗansu alãmõmi -. Archean da Proterozoic.

Height adjustability da kwanciyar hankali na nazarin halittu Tsarin ne kafin for cikakken nazarin halittu juyin halitta. Shi ne su high iya aiki domin karbuwa eukaryotic cell iya bullo a cikin kwayar kwayoyin da hadaddun tsarin kungiyar. Lalle ne, a cikin kwayar halitta da tsarin, sel tare da wannan genome, adapting to canza yanayi, samar da wani mabanbanta, duka a cikin morphological Properties, da kuma ayyuka, yadudduka. Wannan shi ne babban nasara da ci gaba na eukaryotes, wanda ya kai ga zargin da irin wannan babbar iri-iri na rayuwar siffofin a kan duniya da kuma mafita ga juyin fagen fama da mutum da kansa.

A tsarin da Kwayoyin na wani eukaryotic irin na da yawa musamman siffofin waxanda suke ba halayyar prokaryotes. Eukaryotic cell ƙunshi babban adadin kwayoyin abu (90%), wanda aka mayar da hankali a chromosomal Tsarin cewa tsiraru da tabbatar da su a bambance da specialization. Duk wani eukaryotic cell halin da raba core. Wannan shi ne babban bayãnin hukuncin alama na da irin wannan Kwayoyin. Wani muhimmin bambanci daga prokaryotes ne da wasu gabbansa da eukaryotic Kwayoyin - wani iri-iri na dindindin da kuma kwayuka Tsarin.

Eukaryotic cell, idan aka kwatanta da prokaryotic yana da wani hadadden multistage tsarin na ji na daban-daban abubuwa. A yanayi akwai wasu hankula duniya eukaryotic cell irin. Dukan su ne halin da m bambancin cewa shi ne saboda daidai da bukatar wani juyin karbuwa. A muhimmanci sosai alama na eukaryotes ne su muhimmi compartmentalisation - sarrafawa dukkan biochemical matakai a cikin mutum salula compartments, rabu da kwayuka membrane. Eukaryotes da yawa hadaddun tsarin aka gyara. Kamar da membrane tsarin. cytoplasmic matrix, wanda shi ne babban kwayuka abu. salula da wasu gabbansa - babban aikin gyara na eukaryotes.
