txheej txheem nyob rau hauv uas ib feem ntawm nucleotide ib theem zuj zus ntawm DNA yog theej rau hauv ib qho kev sib txuas ua ke hauv tub txib RNA . Lub mRNA tuaj yeem tawm mus sab nraud ntawm lub nucleus thiab mus rau ribosomes. tus txheej txheem yog cov ntaub ntawv genetic coded nyob rau hauv messenger RNA directs tsim ib tug tshwj xeeb protein ntau ntawm ribosome hauv cytoplasm.

Ib yam li ntawd, koj tuaj yeem nug, lub xov tooj ntawm tes siv ob qho tib si DNA thiab RNA li cas los tswj cov protein synthesis quizlet?

Thaum transcription, RNA polymerase khi rau DNA thiab cais cov DNA strands. RNA tom qab ntawd polymerase siv ib strn DNA raws li tus qauv los ntawm cov nucleotides tau sib sau ua ke rau hauv ib txoj hlua ntawm RNA . Thaum lub sij hawm txhais lus, lub cell siv cov ntaub ntawv los ntawm messenger RNA tsim tawm cov proteins . protein ntau.

Tsis tas li ntawd, hom RNA twg koom nrog hauv cov lus nug ntawm cov protein synthesis? ribosomal ua RNA yog ua ke nrog cov proteins . dab tsi yog lub luag hauj lwm ntawm tub txib RNA molecules? mRNA nqa cov ntawv luam ntawm cov lus qhia rau kev sib sau cov amino acids rau hauv cov proteins . Lawv coj cov lus qhia los ntawm DNA mus rau lwm lub cell.

Tsis tas li, hom RNA twg koom nrog hauv kev tsim cov protein?

Muaj peb hom RNA ncaj qha koom nrog hauv cov protein synthesis:

  • Neeg xa xov liaison RNA (mRNA) nqa cov lus qhia los ntawm lub nucleus mus rau cytoplasm.
  • Lwm ob hom ntawm RNA, ribosomal RNA (rRNA) thiab hloov RNA (tRNA), yog koom nrog hauv cov txheej txheem ntawm kev xaj cov amino acids los ua cov protein.

Puas yog cov txheej txheem los ntawm cov ntaub ntawv caj ces hauv DNA yog siv rau kev tsim cov protein?

Cov Cov ntaub ntawv hauv DNA Txiav txim siab Cellular Function ntawm Kev txhais lus . Los tsim protein ntau molecules, ib tug cell yuav tsum xub hloov cov ntaub ntawv los ntawm DNA los ntawm mRNA txheej txheem ntawm kev sau ntawv . Tom qab ntawd, a txheej txheem hu ua siv txhais lus no mRNA raws li ib tug template rau protein ntau kev sib dhos.
