Ib lub ribosome txuas rau mRNA hauv cytoplasm. Ntawm ribosome, mRNA muab cov cai rau cov protein ntau uas yuav ua. Hauv cytoplasm, cov amino acids tshwj xeeb yog txuas rau cov molecules tshwj xeeb. Tom qab ntawd, tRNA txuas rau mRNA.
Xav txog qhov no, lub cell ua cov protein li cas?
Thaum lub cell xav tau ua a protein ntau , mRNA yog tsim nyob rau hauv lub nucleus. Tom qab ntawd, mRNA raug xa tawm ntawm lub nucleus thiab mus rau ribosomes. Thaum twg los tau ua tus protein ntau , ob lub subunits tuaj ua ke thiab ua ke nrog mRNA. tRNA yog sib koom ua ke rau cov amino acids ntab ncig lub cell.
Tsis tas li ntawd, vim li cas cov hlwb yuav tsum ua cov protein? Cov protein yog cov loj, complex molecules uas ua si ntau lub luag haujlwm tseem ceeb hauv lub cev. Lawv ua feem ntau ntawm kev ua haujlwm hauv hlwb thiab yuav tsum muaj rau cov qauv, kev ua haujlwm, thiab kev tswj hwm ntawm lub cev cov ntaub so ntswg thiab cov kabmob. Enzymes nqa tawm yuav luag tag nrho ntawm ntau txhiab tus tshuaj tiv thaiv uas tshwm sim hauv hlwb.
Ib yam li ntawd, cov hlwb paub li cas cov proteins los ua quizlet?
Thaum protein ntau syntheis, ua hlwb siv cov ntaub ntawv los ntawm cov noob ntawm chromosome rau tsim tawm ib qho tshwj xeeb protein ntau . DNA unzips ntawm nws lub hauv paus khub. Tom qab ntawd ib qho ntawm cov strands ntawm DNA qhia qhov tsim tawm ntawm mRNA strands. DNA thiab RNA yuav tsum tau ua ke.
Puas yog txhua lub cell tsim cov protein?
Cov protein yog loj, complex molecules, uas tag nrho koj hlwb ua tsis tu ncua. Txhua protein ntau yog tsim los ntawm ntau cov amino acids uas yuav tsum tau koom ua ke hauv kev txiav txim kom raug protein ntau ua haujlwm kom raug. Phau ntawv qhia no yog nyob rau hauv koj cov noob - pom nyob rau hauv lub cell nucleus.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Yuav ua li cas cov hlwb tsim thiab tso cov proteins?
Thaum lub cell yuav tsum tau ua ib tug protein, mRNA yog tsim nyob rau hauv lub nucleus. Tom qab ntawd, mRNA raug xa tawm ntawm lub nucleus thiab mus rau ribosomes. Nrog rau mRNA muab cov lus qhia, ribosome txuas mus rau tRNA thiab rub tawm ib qho amino acid. Tom qab ntawd tRNA tso tawm rov qab rau hauv lub cell thiab txuas mus rau lwm cov amino acid
Vim li cas cov cell membrane yuav tsum tau thauj cov proteins?
Kev piav qhia: Lawv pab cov molecules thoob plaws hauv daim nyias nyias ntawm kev thauj mus los, ib txoj kev hu ua kom yooj yim diffusion. Cov proteins no yog lub luag haujlwm rau nqa ions thiab lwm cov molecules me rau 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 cog cell txawv ntawm cov tsiaj cell?
Qhov sib txawv ntawm cov nroj tsuag thiab cov tsiaj hlwb yog tias cov tsiaj txhu feem ntau yog puag ncig thaum cov nroj tsuag feem ntau yog cov duab plaub. Cov nroj tsuag muaj cov phab ntsa tawv tawv uas nyob ib puag ncig cov cell membrane. Tsiaj cell tsis muaj phab ntsa ntawm tes
