Tom qab mRNA yog synthesized los ntawm DNA thaum transcription, tus tshiab molecule txav los ntawm lub nucleus mus rau lub cytoplasm, dhau los ntawm nuclear membrane los ntawm ib tug nuclear pore. Ribosomes yog qhov chaw ntawm kev txhais lus, lossis siv cov ntaub ntawv hauv mRNA los tsim cov protein sib xws.
Xav txog qhov no, ua li cas mRNA tawm ntawm lub nucleus?
Messenger RNA, los yog mRNA , tawm lub nucleus los ntawm cov pores nyob rau hauv lub nuclear membrane. Cov pores no tswj kev nkag ntawm cov molecules ntawm cov nucleus thiab cytoplasm. mRNA Kev ua haujlwm tsuas yog tshwm sim hauv eukaryotes.
Ib sab saum toj no, mRNA ua li cas tawm hauv cov lus nug nucleus? Cov mRNA tawm ntawm nucleus ntawm lub qhov pores ntawm nuclear, mus rau hauv cytoplasm rau kev txhais lus. Piav cov txheej txheem ntawm kev txhais lus. Hloov mRNA mus rau hauv cov proteins thiab tshwm sim nyob rau hauv lub cytoplasm, nrog kev pab los ntawm ribosomes ntawm ntxhib Endoplasmic reticulum thiab dawb nyob rau hauv lub cytoplasm.
Tsis tas li, mRNA thauj mus li cas?
mRNA tsim nyob rau hauv lub nucleus yog thauj tawm ntawm lub nucleus thiab mus rau hauv cytoplasm qhov twg nws txuas rau ribosomes. Proteins yog sib sau ua ke ntawm ribosomes siv lub mRNA nucleotide raws li kev qhia. Yog li, mRNA nqa ib "lus" los ntawm lub nucleus mus rau cytoplasm.
Tus qauv ntawm mRNA yog dab tsi?
Cov qauv ntawm ib tug paub tab eukaryotic mRNA . Kev ua tiav tiav mRNA suav nrog 5 'cap, 5' UTR, coding cheeb tsam, 3' UTR, thiab poly(A) tail.

Dab tsi organelle yog lub luag haujlwm rau kev thauj khoom hauv thiab tawm ntawm lub cell?
Function Of Cell Organelles A B cell membrane tswj kev txav mus rau hauv thiab tawm ntawm lub cell cytoplasm watery khoom uas muaj ntau cov ntaub ntawv koom nrog hauv cell metabolism endoplasmic reticulum ua txoj hauv kev rau kev thauj khoom thoob plaws hauv lub cell
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Yuav ua li cas koj pom qhov nruab nrab tshaj tawm ntawm qhov tshaj tawm vs lub sijhawm teeb?
Qhov chaw nyob hauv qab qhov nrawm / lub sijhawm nkhaus yog tag nrho cov kev hloov pauv. Yog tias koj faib qhov ntawd los ntawm kev hloov pauv hauv lub sijhawm, koj yuav tau txais qhov nruab nrab tshaj tawm. Velocity yog vector daim ntawv ntawm kev ceev. Yog tias qhov nrawm ib txwm tsis yog qhov tsis zoo, ces qhov nruab nrab tshaj tawm thiab qhov nruab nrab ceev yog tib yam
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
Yuav ua li cas mRNA tawm nucleus?
Kev piav qhia: Neeg xa xov liaison RNA, los yog mRNA, tawm hauv lub nucleus los ntawm qhov hws hauv daim nyias nyias. Cov pores no tswj kev nkag mus ntawm cov molecules ntawm cov nucleus thiab cytoplasm. mRNA kev ua haujlwm tsuas yog tshwm sim hauv eukaryotes
