Prions yog cov kab mob sib kis uas tsis muaj cov nucleic acids, thiab viroids yog cov kab mob me me uas tsis encode proteins.
Puas yog viroids thiab prions microbes?
Viroids muaj me me, liab qab ssRNAs uas ua rau muaj kab mob hauv cov nroj tsuag. Virusoids yog ssRNAs uas xav tau lwm cov kab mob uas pab tsim kom muaj kab mob. Prions yog cov proteinaceous kis kab mob uas ua rau kis tau spongiform encephalopathies. Prions tiv taus tshuaj lom neeg, tshav kub, thiab hluav taws xob.
Puas prions thiab viroids nyob?
Kab mob, prions thiab viroids yog cov kab mob tsis muaj sia uas xav tau tus tswv tsev nyob hauv cellular thiaj li tsim tau. Lawv ua tsis tau rau lawv tus kheej. Cov kab mob no tsuas yog ib txoj hlua ntawm RNA, ib yam li hauv viroid, lossis ntev ntawm DNA nyob rau hauv lub plhaub protein, xws li hauv tus kab mob.
prions thiab kab mob sib txawv li cas?
Prions me dua cov kab mob thiab tsuas pom tau los ntawm lub tshuab ntsuas hluav taws xob thaum lawv tau sib sau ua ke thiab tsim ib pawg. Prions kuj tseem tshwj xeeb uas lawv tsis muaj nucleic acid, tsis zoo li cov kab mob, fungi, kab mob, thiab lwm yam kab mob.
pom kab mob viroids nyob qhov twg?
Viroids yog cov nroj tsuag kab mob nrog kev lag luam tseem ceeb. Viroid genomes yog qhov me me, tsuas yog li 300 nucleotides. Viroids tau pom nyob rau hauv cov khoom ua liaj ua teb, xws li qos yaj ywm, txiv lws suav, txiv apples, thiab txiv maj phaub.
