Piav: Neeg xa xov liaison RNA, los yog mRNA , nplooj tus 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.

Kuj nug, ua li cas mRNA tawm ntawm lub nucleus quizlet?

Cov mRNA tawm ntawm nucleus los ntawm cov pores nuclear, mus rau hauv cytoplasm rau 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.

Ib yam li ntawd, puas yog mRNA hauv lub nucleus? mRNA yog "tus tub txib" RNA. mRNA yog synthesized nyob rau hauv lub nucleus siv cov nucleotide ua ntu zus ntawm DNA ua tus qauv. mRNA tsim nyob rau hauv lub nucleus yog thauj tawm ntawm nucleus Thiab nyob rau hauv lub cytoplasm qhov twg nws txuas mus rau lub ribosomes.

Hauv qhov no, thaum mRNA tawm ntawm lub nucleus nws mus qhov twg?

Transcription yuav siv sij hawm qhov chaw nyob rau hauv lub nucleus . Nws siv DNA ua tus qauv los ua RNA molecule. RNA tiam tawm lub nucleus thiab mus mus rau ib tug ribosome nyob rau hauv lub cytoplasm, qhov twg translation tshwm sim. Kev txhais lus nyeem cov noob caj noob ces hauv mRNA thiab ua ib protein.

Vim li cas mRNA tuaj yeem tawm hauv cov nucleus thiab DNA tsis tuaj yeem?

DNA , uas muaj peb cov noob caj noob ces, nyob rau hauv lub nucleus ntawm cov kab mob eukaryotic. DNA tsis tuaj yeem tawm hauv lub nucleus , thiab yog li xa cov lus qhia mus rau tus so ntawm tes nws yuav tsum tau replicated, tsim mRNA , qho tuaj yeem tawm ntawm lub nucleus.
