Frameshift mutations tshwm sim thaum qhov ib txwm ua ntawm codons cuam tshuam los ntawm kev ntxig lossis tshem tawm ntawm ib lossis ntau dua nucleotides, muab cov nucleotides ntxiv lossis tshem tawm tsis yog ntau yam. ntawm peb.
qhov hloov pauv hloov pauv tshwm sim nyob qhov twg?
Frameshift kev hloov pauv tuaj yeem tshwm sim los ntawm tshem tawm lossis tso cov nucleotide hauv cov nucleic acid (Daim duab 3). Kev hloov pauv hloov pauv, qhov twg ib lossis ntau dua nucleotides raug tshem tawm hauv nucleic acid, ua rau hloov pauv ntawm cov ntawv nyeem, piv txwv li, nyeem ntawv frameshift, ntawm nucleic acid.
Vim li cas frameshift mutations tshwm sim?
Kev hloov pauv hloov pauv yog tsim los ntawm los ntawm kev ntxig lossis tshem tawm ntawm ib lossis ntau lub hauv paus tshiab. Vim tias qhov kev nyeem ntawv pib ntawm qhov chaw pib, txhua mRNA uas tsim los ntawm cov DNA hloov pauv yuav raug nyeem tawm ntawm tus ncej tom qab lub ntsiab lus ntawm qhov ntxig lossis tshem tawm, ua rau cov protein tsis muaj txiaj ntsig.
Yuav ua li cas taw tes hloov pauv thiab hloov pauv hloov pauv tshwm sim li cas?
Qee cov kws tshawb fawb pom lwm hom kev hloov pauv, hu ua frameshift mutation, ua hom kev hloov pauv. Frameshift mutations tuaj yeem ua rau poob haujlwm tsis zoo thiab tshwm sim los ntawm kev ntxiv lossis tshem tawm ntawm ib lossis ntau dua DNA hauv paus.
Yuav ua li cas thaum hloov pauv hloov pauv tau tsim?
Frameshift Mutation
Txhua pawg ntawm peb lub hauv paus sib raug rau ib qho ntawm 20 qhov sib txawv aminoacids siv los tsim cov protein. Yog tias mutation cuam tshuam qhov kev nyeem ntawv no, ces tag nrho DNA kab ke tom qab mutation yuav nyeem tsis raug.
