ntau tshaj npe, yam lus archae·on [ahr-kee-on]. archaebacteria.

Cov lus nug tseem yog, dab tsi yog archaea hauv kev tshawb fawb?

Archaea , (domain Archaea ), ib pawg ntawm cov kab mob ib leeg-celled prokaryotic (uas yog, cov kab mob uas lawv lub hlwb tsis muaj lub ntsiab lus ntawm lub cev) uas muaj cov yam ntxwv molecular cais lawv los ntawm cov kab mob (lwm yam, ntau pawg ntawm prokaryotes) thiab los ntawm eukaryotes (cov kab mob., suav nrog cov nroj tsuag thiab

Tsis tas li ntawd, qhov twg tuaj yeem pom archaea? Cov kab mob Archaea yog extremophiles nyob rau hauv ib puag ncig hnyav, xws li cov dej kub thiab cov pas dej ntsev, txij li lawv tau pom nyob rau hauv qhov dav. ntau ntawm chaw nyob , nrog rau cov av, dej hiav txwv, marshlands thiab tib neeg txoj hnyuv ces lawv yog ubiquitous.

Tsis tas li ntawd, qhov piv txwv ntawm archaea yog dab tsi?

Piv txwv li: M. Lawv suav nrog acetogens (anaerobic kab mob uas tsim acetate), sulfate-txo kab mob , thiab methogens xws li M. Smithii, feem ntau cov methanogenic archaeon nyob rau hauv tib neeg lub plab thiab ib tug tseem ceeb neeg uas ua ntawv nyob rau hauv lub plab zom mov ntawm polysaccharides (cov suab thaj nyuaj).

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).
