Protein synthesis yog ua tiav los ntawm tus txheej txheem hu ua translation. Tom qab DNA tau sau rau hauv tus xa xov RNA (mRNA) molecule thaum lub sijhawm sau ntawv, mRNA yuav tsum tau muab txhais ua cov protein. Hauv kev txhais lus, mRNA nrog rau kev hloov RNA (tRNA) thiab ribosomes ua haujlwm ua ke los tsim cov protein.
Yuav ua li cas cov proteins thauj los ntawm lub xovtooj tom qab lawv raug tsim tawm?
Yog li ntawd, cov membrane lipids thiab cov proteins uas yog synthesized hauv ER yuav tsum tau thauj mus los ntawm network mus rau lawv qhov chaw kawg hauv daim nyias nyias vesicles. … Thaum lub xovtooj taw qhia los ntawm lub xovtooj, cov hlwv no fuse nrog cov plasma membrane thiab tso lawv cov ntsiab lus mus rau hauv qhov chaw ntxiv.
Yuav ua li cas rau cov proteins thaum lawv raug tsim tawm?
Tom qab raug tsim los, cov protein yuav nqa hauv lub hlwv los ntawm RER mus rau cis ntsej muag ntawm Golgi (sab rau sab hauv ntawm tes). Raws li cov protein txav los ntawm Golgi, nws tuaj yeem hloov kho.
Y Yuav ua li cas cov proteins tuaj yeem ua ke?
Protein synthesis yog txheej txheem uas cov hlwb ua cov protein. Nws tshwm sim nyob rau hauv ob theem: transcription thiab translation. … Kev txhais lus tshwm sim ntawm ribosome, uas muaj rRNA thiab cov proteins. Hauv kev txhais lus, cov lus qhia hauv mRNA tau nyeem, thiab tRNA coj qhov tseeb ntawm cov amino acids mus rau ribosome.
cov proteins thauj li cas?
Los ntawm endoplasmic reticulum, cov proteins raug thauj hauv vesicles mus rau Golgi apparatus, qhov uas lawv tau ua tiav ntxiv thiab txheeb rau kev thauj mus rau lysosomes, plasma membrane, lossis tso tawm los ntawm cov cell.

Puas hloov cov lus piav qhia thiab cov lus teb hloov pauv?
Hloov cov lus piav qhia thiab cov lus teb yuav tsis hloov qhov tsawg kawg-squares regression kab. II. Txoj kab nqes ntawm txoj kab yog rhiab heev rau outliers nyob rau hauv x kev taw qhia nrog loj residuals. … Tus nqi ntawm r^2 ze rau 1 tsis lav tias qhov kev sib raug zoo ntawm qhov sib txawv yog linear.
Yuav ua li cas cov proteins muab tshuaj biuret?
tag nrho peptides thiab protein muab qhov kev sim zoo . Histidine tsuas yog cov amino acid xwb uas muab biuret kuaj pom zoo. Yuav ua li cas cov proteins muab qhov kev kuaj biuret zoo? Txhua cov proteins thiab peptides muab qhov zoo.
Yuav ua li cas cov proteins secretory tsim?
Secretory proteins yog synthesized los ntawm ribosomes txuas rau cisternae ntawm endoplasmic reticulumthiab translocated mus rau lub lumen ntawm endoplasmic reticulum. cov proteins uas zais cia nyob qhov twg? Yog li, los ntawm lub sijhawm cov protein ua tiav nws daim ntawv kawg, nws tau muab tso rau hauv daim nyias nyias (Daim duab 1).
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
