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.
