Muaj nuj nqi ntawm Ribosomes . Ribosomes yog cov qauv cell uas ua rau cov protein. Protein xav tau rau ntau lub cell muaj nuj nqi xws li kho kev puas tsuaj los yog coj cov txheej txheem tshuaj. Ribosomes tuaj yeem pom ntab hauv cytoplasm lossis txuas rau endoplasmic reticulum. Proteins yog ib feem tseem ceeb ntawm txhua lub hlwb.
Tsis tas li lo lus nug yog, ribosome qauv thiab kev ua haujlwm yog dab tsi?
Cov ribosome yog cellular qauv thiab qhov chaw ntawm kev txhais lus, lossis protein synthesis. Nws yog tsim los ntawm rRNA thiab protein. Ib tug txhais ribosome tuaj yeem ua nws muaj nuj nqi dawb nyob rau hauv lub cytoplasm los yog khi rau endoplasmic reticulum. Ib txhia cov ribosomes tseem nyob hauv cov qauv hu ua mitochondria thiab chloroplasts.
Tsis tas li ntawd, ribosomes hauv biology yog dab tsi? -sōm'] Ib tug kheej kheej-zoo li tus qauv nyob rau hauv lub cytoplasm ntawm ib tug cell uas yog tsim ntawm RNA thiab protein thiab yog qhov chaw ntawm protein synthesis. Ribosomes yog dawb nyob rau hauv lub cytoplasm thiab feem ntau txuas mus rau daim nyias nyias ntawm endoplasmic reticulum. Ribosomes muaj nyob rau hauv ob qho tib si eukaryotic thiab prokaryotic hlwb.
Ib sab saum toj no, dab tsi yog lub luag haujlwm tseem ceeb ntawm cov dawb ribosomes?
Ribosomes tseem ceeb heev vim lawv muaj lub luag haujlwm rau protein ntau synthesis. Dawb ribosomes, tshwj xeeb, tseem ceeb heev vim lawv tsim cov proteins Qhov tseem ceeb rau kev ua haujlwm hauv cellular, uas tsis yog synthesized nyob rau lwm qhov.
Dab tsi ua rau ribosomes hauv cell?
Qee cov chromosomes muaj cov seem ntawm DNA uas encode ribosomal RNA, ib hom qauv RNA uas ua ke nrog cov proteins los ua kom cov ribosomal RNA. ribosome . Nyob rau hauv lub nucleolus, tshiab ribosomal RNA ua ke nrog cov proteins los tsim cov subunits ntawm lub ribosome.

Dab tsi yog cytoplasm thiab nws txoj haujlwm?
Nws yog tsim los ntawm feem ntau dej thiab ntsev. Cytoplasm muaj nyob rau hauv lub cell membrane ntawm txhua hom cell thiab muaj tag nrho cov organelles thiab cell seem. Cytoplasm muaj ntau yam haujlwm hauv lub cell. Cytoplasm yog lub luag haujlwm rau muab lub cell nws cov duab. Nws pab sau cov cell thiab khaws cov organelles hauv lawv qhov chaw
Dab tsi yog photosynthesis thiab nws txoj haujlwm?
Lub luag haujlwm tseem ceeb ntawm photosynthesis yog hloov lub zog ntawm lub hnub mus rau hauv lub zog tshuaj rau zaub mov. Tsuas yog qee cov nroj tsuag siv chemosynthesis, tag nrho cov nroj tsuag thiab tsiaj txhu hauv ntiaj teb ecosystem yog qhov kawg nyob ntawm cov suab thaj thiab carbohydrates uas tsim los ntawm cov nroj tsuag los ntawm photosynthesis
Dab tsi yog cov qauv ntawm DNA thiab nws txoj haujlwm?
DNA yog cov ntaub ntawv molecule. Nws khaws cov lus qhia ua rau lwm cov molecules loj, hu ua cov proteins. Cov lus qhia no tau khaws cia rau hauv txhua lub hlwb, faib ntawm 46 cov qauv ntev hu ua chromosomes. Cov chromosomes no yog tsim los ntawm ntau txhiab ntu luv ntawm DNA, hu ua noob
Lub cell membrane thiab nws txoj haujlwm yog dab tsi?
Lub cell membrane yog ib tug multifaceted membrane uas envelopes ib lub cell lub cytoplasm. Nws tiv thaiv kev ncaj ncees ntawm tes nrog rau kev txhawb nqa ntawm tes thiab pab tswj lub cell zoo li qub. Proteins thiab lipids yog cov khoom tseem ceeb ntawm cov cell membrane
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
