Ib mob cell tsim ntau dua kab mob protein thiab genetic khoom es tsis txhob ntawm nws cov khoom ib txwm. Ib txhia kab mob tuaj yeem nyob twj ywm hauv tus tswv tsev hlwb rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv tus tswv tsev hlwb (ib theem hu ua lysogenic theem). Kab mob ua rau ib tug xov tooj ntawm cov kab mob nyob rau hauv eukaryotes.
Ib yam li ntawd, cov kab mob eukaryotic puas yog?
Kab mob raug suav hais tias tsis yog prokaryotes lossis eukaryotes vim tias lawv tsis muaj cov yam ntxwv ntawm cov khoom muaj sia, tsuas yog muaj peev xwm rov ua dua tshiab (uas lawv ua tiav hauv cov hlwb nkaus xwb).
Tsis tas li ntawd, cov kab mob puas muaj hlwb? A kab mob vais lav yog ib qho me me, kis kab mob uas tuaj yeem tsim tau tsuas yog los ntawm kev kis tus kabmob ntawm tus tswv tsev. Tsis yog puas muaj kab mob : lawv me me, ntau me dua li hlwb ntawm cov khoom muaj sia, thiab tsuas yog pob khoom ntawm nucleic acid thiab protein. Tseem, cov kab mob muaj qee qhov tseem ceeb hauv kev sib txuam nrog lub neej ntawm tes.
Ua kom pom qhov no, cov kab mob tuaj yeem kis tau cov kab mob prokaryotic?
Cov kab mob uas nyob hauv mammalian hosts ua tau yuav tsum tau muab faib ua bacteriophages, uas kis cov kab mob prokaryotic ; eukaryotic tshuaj kab mob , qho kis tau tus tswv tsev thiab lwm yam eukaryotic hlwb ; thiab kab mob vais lav - muab genetic ntsiab, uas ua tau koom ua ke rau hauv tus tswv chromosomes thiab ua rau muaj kev sib kis kab mob vais lav tom qab
Puas yog cov kab mob bacteriophages kis cov kab mob eukaryotic?
Yog li, nws tsis cuam tshuam rau tib neeg cell . Yog peb pom lub mechanism uas kab mob bacteriophage lawv tus tswv xws li cov kab mob, lawv txuas lawv tus kheej mus rau cov receptors tshwj xeeb tam sim no ntawm cov kab mob cell phab ntsa. Cov receptors no tshwj xeeb rau cov kab mob. Yog li qhov no yog thawj barrier rau lawv nkag rau hauv lub eukaryotic tshuaj tus tswv tsev.

Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
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
