Archaea - thaum lub sijhawm ntawd tsuas yog cov tshuaj methanogens paub - tau muab cais ua ntej cais los ntawm kab mob Xyoo 1977 los ntawm Carl Woese thiab George E. Fox raws li lawv cov ribosomal RNA (rRNA) noob.
Tsis tas li ntawd, Archaea thawj qhov txawv ntawm lwm cov prokaryotes li cas?
Zoo sib xws ntawm lawv. Archaea thiab kab mob yog ob leeg prokaryotes , txhais tau tias lawv tsis ua muaj ib tug nucleus thiab tsis muaj membrane-bound organelles. Lawv yog me me, ib leeg-cell kab mob uas tsis tuaj yeem pom los ntawm qhov muag liab qab tib neeg hu ua microbes.
Ib yam li ntawd, qhov txawv ntawm cov kab mob thiab archaea yog dab tsi? Qhov txawv ntawm Archaea thiab Kab mob . Archea muaj peb RNA polymerases zoo li eukaryotes, tab sis kab mob muaj ib leeg xwb. Archaea muaj cov phab ntsa ntawm tes uas tsis muaj peptidoglycan thiab muaj daim nyias nyias uas ntim cov lipids nrog hydrocarbons es tsis yog fatty acids (tsis yog bilayer).
Kuj paub yog, thaum twg thawj Archaea tshwm sim?
3.5 billion xyoo dhau los
Thaum twg archaea thiab kab mob sib cais?
3.7 billion xyoo dhau los

Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Tus kab mob puas yog kab mob multicellular?
Cov kab mob tsis raug cais raws li cov hlwb thiab yog li ntawd tsis muaj unicellular los yog multicellular kab mob.Viruses muaj genomes uas muaj xws li DNA los yog RNA, thiab muaj cov piv txwv ntawm cov kab mob uas yog ob leeg-stranded los yog ib leeg-stranded
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Puas yog cov kab mob unicellular kab mob?
Tus Kab Mob Qhov Twg Zoo? Cov kab mob tsis raug cais raws li cov hlwb thiab yog li tsis yog unicellular lossis multicellular kab mob. Cov kab mob muaj cov genomeshat muaj xws li DNA lossis RNA, thiab muaj cov piv txwv ntawm cov kab mob uas yog ob leeg-stranded orsingle-stranded
Cov kab mob puas yog ib hom kab mob ntawm tes?
Teb thiab piav qhia: Cov kab mob no tsis suav tias yog cov cell nyob thiab yog li ntawd tsis yog ib leeg-celled lossis ntau-celled. Lawv tsuas yog suav hais tias yog cov plhaub protein
