Archaea , ( sau Archaea ), ib pawg ntawm cov kab mob ib leeg-celled prokaryotic (uas yog, cov kab mob uas lawv lub hlwb tsis muaj ib qho txhais nucleus) uas muaj cov yam ntxwv molecular sib cais lawv los ntawm cov kab mob (lwm, ntau pab pawg ntawm prokaryotes) thiab los ntawm eukaryotes (cov kab mob, nrog rau cov nroj tsuag thiab
Sib tham, koj txhais li cas los ntawm archaea?
Plural archaea ua Ib pawg ntawm cov kab mob uas zoo li cov kab mob tab sis yog txawv ntawm lawv nyob rau hauv lawv cov genetic pleev thiab tej yam ntawm lawv cell qauv, xws li cov muaj pes tsawg leeg ntawm lawv cov phab ntsa cell.
Qhov thib ob, dab tsi yog qee qhov piv txwv ntawm archaea kab mob? Archaea yog unicellular kab mob uas ua rau lub thib peb domain kab mob nyob ntiaj teb.
Qee qhov piv txwv suav nrog:
- Aeropyrum pernix.
- Thermosphaera aggregans.
- Ignisphaera aggregans.
- Sulfolobus tseem ceeb.
- Metallosphaera sedula.
- Staphylothermus marinus.
- Thermoproteus tenax.
Thiab cov lus nug yog, dab tsi yog 3 piv txwv ntawm Archaea?
Muaj peb loj paub pawg ntawm Archaebacteria : Methanogens, halophiles, thiab thermophiles. Methanogens yog cov kab mob anaerobic uas tsim methane. Lawv muaj nyob rau hauv cov dej phwj tuaj kho cov nroj tsuag, bogs, thiab cov hnyuv ntawm ruminants. Ancient methanogens yog lub hauv paus ntawm natural gas.
Dab tsi yog qhov txawv ntawm cov kab mob thiab archaea?
Ob leeg kab mob thiab archaea muaj txawv Ribosomal RNAs (rRNA). 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).
