Prokaryotic cell yog ntau me dua eukaryotic hlwb , muaj tsis muaj nucelus, thiab tsis muaj organelles. Tag nrho cov cell prokaryotic encased ib cell phab ntsa. Feem ntau prokaryotic hlwb muaj ib ncig chromosome. Lawv kuj yuav muaj me me ntawm ncig DNA hu ua plasmids.
Ib yam li ntawd, tib neeg nug, puas hlwb prokaryotic muaj DNA?
Prokaryotic hlwb (Daim duab hauv qab no) feem ntau me me thiab yooj yim dua eukaryotic hlwb . Lawv ua tsis yog muaj ib tug nucleus los yog lwm yam membrane-bound organelles. Hauv prokaryotic hlwb , cov DNA , los yog cov khoom siv caj ces, tsim ib lub voj voog loj uas coils ntawm nws tus kheej. Cov DNA yog nyob rau hauv lub ntsiab ntawm lub cell.
Kuj Paub, hom plasmids muaj nyob rau hauv prokaryotes? Muaj tsib lub ntsiab hom plasmids : Fertility F- plasmids , tsis kam plasmids , kev ua phem plasmids , degradative plasmids , thiab Col plasmids.
Tib neeg kuj nug, DNA ua dab tsi hauv lub cell prokaryotic?
Cov DNA hauv yog prokaryotes muaj nyob rau hauv ib tug central cheeb tsam ntawm lub cell hu ua nucleoid, uas yog tsis nyob ib puag ncig los ntawm ib tug nuclear membrane. Ntau prokaryotes kuj nqa me me, ncig DNA molecules hu ua plasmids, uas yog txawv ntawm chromosomal DNA thiab ua tau muab cov txiaj ntsig zoo ntawm caj ces hauv ib puag ncig tshwj xeeb.
plasmid DNA yog dab tsi thiab nws ua haujlwm li cas hauv prokaryotes uas muaj nws?
Plasmids . Ib txhia prokaryotes kuj nqa cov voj voog me me ntawm DNA hu ua plasmids . Cov ntaub ntawv genetic ntawm lub plasmids yog hloov ntawm cov hlwb, tso cai prokaryotes los qhia tej peev xwm xws li tshuaj tiv thaiv kab mob. Tib neeg tau pom qhov ntawd prokaryotic plasmids tuaj yeem ua tau yuav genetic engineered.

Dab tsi yog pom hauv eukaryotic hlwb tab sis tsis yog cov hlwb prokaryotic?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, xws li cov nucleus, thaum cov hlwb prokaryotic tsis ua. Qhov sib txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes muaj xws li muaj mitochondria thiab chloroplasts, phab ntsa cell, thiab cov qauv ntawm chromosomal DNA
Cov qauv twg muaj nyob hauv cov hlwb prokaryotic?
Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Cov cell prokaryotic tsis muaj cov nucleus thiab cov txheej txheem sib khi
Dab tsi yog qhov txawv ntawm prokaryotic thiab eukaryotic hlwb hlwb?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, nrog rau cov nucleus. Eukaryotes tuaj yeem ua ib leeg lossis ntau lub hlwb, xws li koj, kuv, nroj tsuag, fungi, thiab kab. Cov hlwb prokaryotic tsis muaj cov nucleus lossis lwm cov kab mob sib txuas ua ke
Vim li cas cov hlwb muaj peev xwm sib txuas lus nrog lwm cov hlwb tseem ceeb?
Cov kev sib cuam tshuam no tso cai rau cov hlwb sib txuas lus nrog ib leeg hauv kev teb rau kev hloov pauv hauv lawv cov microenvironment. Qhov kev muaj peev xwm xa thiab tau txais cov teeb liab yog qhov tseem ceeb rau kev muaj sia nyob ntawm tes. Kev sib cuam tshuam ntawm cov hlwb tuaj yeem ruaj khov xws li cov uas ua los ntawm cov xov tooj ntawm tes
Dab tsi yog qhov txawv ntawm cov hlwb prokaryotic thiab prokaryotic?
Prokaryotes yog cov kab mob uas tsim los ntawm cov hlwb uas tsis muaj cell nucleus los yog ib qho membrane-encased organelles. Eukaryotes yog cov kab mob uas tsim los ntawm cov hlwb uas muaj cov membrane-bound nucleus uas tuav cov khoom siv noob caj noob ces nrog rau cov kab mob membrane-bound organelles
