Prokaryotic transcription thiab translation tshwm sim ib txhij nyob rau hauv lub cytoplasm, thiab kev cai tshwm sim nyob rau theem transcriptional Eukaryotic noob qhia yog tswj thaum lub sij hawm transcription thiab RNA ua, uas tshwm sim nyob rau hauv lub nucleus, thiab thaum lub sij hawm txhais lus protein, uas tshwm sim nyob rau hauv lub cytoplasm.
Kev tswj kev hloov pauv nyob qhov twg?
In Summary: Post-TransCRIPTIONAL Control of Gene Expression
Post-transcriptional control tuaj yeem tshwm sim ntawm txhua theem tom qab kev sau ntawv, suav nrog RNA splicing, nuclear shuttling, thiab RNA stability. Thaum RNA tau sau tseg, nws yuav tsum tau ua tiav los tsim RNA paub tab uas npaj tau los txhais.
Txoj cai txhais lus tshwm sim nyob qhov twg?
Kev pib txhais lus yog tswj hwm los ntawm nkag mus ntawm ribosomes rau Shine-Dalgarno sequence Qhov kev ncab ntawm plaub mus rau cuaj purine residues nyob rau ntawm qhov pib codon thiab hybridize mus rau pyrimidine - nplua nuj nyob ze ntawm 3' kawg ntawm 16S RNA hauv 30S kab mob ribosomal subunit.
Kev tswj hwm noob caj noob ces nyob qhov twg?
Txoj cai tom qab kev hloov pauv yog kev tswj cov noob qhia ntawm qib RNA. Nws tshwm sim ib zaug RNA polymerase tau txuas nrog cov noob tus txhawb nqathiab tau ua ke cov nucleotide ib ntus.
kev cai tshwm sim nyob qhov twg?
Gene regulation tuaj yeem tshwm sim ntawm txhua qhov chaw thaum lub sij hawm gene qhia, tab sis feem ntau tshwm sim nyob rau theem ntawm kev hloov pauv (thaum cov ntaub ntawv hauv cov noob DNA tau dhau mus rau mRNA). Cov teeb liab los ntawm ib puag ncig lossis los ntawm lwm lub hlwb ua kom cov proteins hu ua transcription factor.

Kev hloov pauv tshwm sim nyob qhov twg hauv dna?
Kev hloov pauv tuaj yeem tshwm sim los ntawm DNA luam yuam kev thaum lub sijhawm faib cell, raug ionizing hluav taws xob, raug rau cov tshuaj hu ua mutagens, lossis kis los ntawm cov kab mob. Kab mob kab mob tshwm sim hauv qe thiab phevthiab tuaj yeem kis mus rau cov xeeb ntxwv, thaum somatic kev hloov pauv tshwm sim hauv lub cev hlwb thiab tsis dhau mus .

Thaum twg qhov kev hloov pauv hloov pauv tau tsim nyog?
Thaum twg Stepwise Regression tsim nyog? Stepwise regression yog ib qho kev ntsuam xyuas tsim nyog thaum koj muaj ntau qhov sib txawv thiab koj txaus siab txheeb xyuas qhov muaj txiaj ntsig ntawm cov kwv yeesHauv Minitab, tus txheej txheem kev hloov pauv theem ob ntxiv thiab tshem tawm cov kwv yees ib ntawm ib qho.
Cov siphons tshwm sim thiab tshwm sim nyob qhov twg?

Qhov twg hauv qab no tau tshwm sim los ntawm kev hloov pauv kev ua liaj ua teb?
Qhov twg hauv qab no tau tshwm sim los ntawm kev hloov pauv kev ua liaj ua teb? Ntau tus neeg ua liaj ua teb me tau los ua cov neeg ua liaj ua teb lossis tsiv mus rau hauv nroog, cov ntaub thaiv tau dhau los ua qhov chaw ntawm cov tswv av nplua nuj, cov tswv av tau sim cov txheej txheem ua liaj ua teb tshiab.
