Bacteriophages , luv form: phages (Greek: phagein = noj / nqos) yog cov kab mob hauv qhov dav dav dav. Lawv tsuas tua kab mob thiab lyse lawv ( kab mob cov neeg noj mov”). Phaj tsis tuaj yeem tsim ib leeg los ntawm lawv tus kheej, lawv xav tau kab mob cell ua a tus tswv tsev los tsim nyob rau hauv lub tus tswv tsev.
Ib yam li ntawd, koj tuaj yeem nug, puas yog tus tswv tsev tshwj xeeb?
Bacteriophages (" phages " luv luv) yog cov kab mob uas kis kab mob. Phaj yog heev tus tswv tsev - tshwj xeeb thiab feem ntau yuav kis tau thiab tua ib tug tus kheej hom kab mob los yog kab mob subspecies. Piv nrog rau cov tshuaj tua kab mob, phages tsis txhob tua kab mob indiscriminately.
Kuj Paub, yog vim li cas phages tshwj xeeb rau lawv cov tswv tsev cell? BACTERIOPHAGES . Bacteriophages ( phages ) yog cov kab mob uas kis kab mob hlwb . Lawv tuaj yeem yog pom hauv txhua qhov chaw nyob qhov twg lawv kab mob tus tswv tsev muaj nyob. Phaj txuas rau a host cell yog ib tug heev tshwj xeeb cov txheej txheem cuam tshuam nrog cov receptors ntxiv rau ntawm qhov chaw raug host cell thiab kis tus kab mob.
Ib yam li ntawd, vim li cas cov phage tshwj xeeb rau qee hom kab mob?
Txhawm rau nkag mus rau tus tswv cell, cov kab mob bacteriophages txuas rau tshwj xeeb receptors nyob rau saum npoo ntawm kab mob . Qhov tshwj xeeb no txhais tau tias a kab mob bacteriophage tsuas kis tau tej kab mob bearing receptors uas lawv yuav khi, uas nyob rau hauv lem txiav txim lub phage ua host ntau.
Tus tswv tsev ntawm bacteriophage yog dab tsi?
A kab mob bacteriophage yog ib hom kab mob uas kis kab mob. Qhov tseeb, lo lus " kab mob bacteriophage "lus txhais tau tias "tus kab mob noj," vim cov kab mob bacteriophages rhuav tshem lawv tus tswv tsev hlwb. Tag nrho cov kab mob bacteriophages yog tsim los ntawm nucleic acid molecule uas yog surrounded los ntawm cov qauv protein.

Dab tsi yog hom kab mob tshwj xeeb?
Ua ke ob lo lus tsim lub npe scientific ntawm aunique hom kab mob. Ib hom yog ib pawg ntawm cov kab mob zoo sib xws uas tuaj yeem sib koom ua ke thiab tsim cov xeeb ntxwv uas tuaj yeem ua phooj ywg thiab rov tsim dua. Prokaryotes yog cov kab mob unicellular uas lub cell tsis muaj lub cev
Yuav ua li cas cov cell nyob rau hauv ib tug multicellular kab mob ua tshwj xeeb?
Cellular sib txawv yog cov txheej txheem uas ib tug tsawg tshwj xeeb cell ua ib tug tshwj xeeb cell hom. Kev sib txawv tshwm sim ntau zaus thaum lub sij hawm kev loj hlob ntawm ib tug multicellular kab mob raws li lub cev hloov los ntawm ib tug yooj yim zygote mus rau ib tug complex system ntawm cov ntaub so ntswg thiab cell hom
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
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
