A frameshift kev hloov (tseem hu ua framingerror lossis nyeem ntawv ncej hloov ) yog genetic kev hloov pauv tshwm sim los ntawm indels (insertions los yog deletions) ntawm ib tug xov tooj ntawm nucleotides nyob rau hauv ib tug DNA theem uas tsis divisible los ntawm peb. Atype ntawm kev hloov pauv qhov twg ib ntu ntawm DNA tau hloov ntawm ib chromosome mus rau lwm qhov.
Tib neeg kuj nug, qhov sib txawv ntawm qhov kev hloov pauv ntawm qhov taw tes thiab qhov kev hloov pauv hloov pauv yog dab tsi?
A kev hloov pauv uas tshwm sim los ntawm kev hloov hauv ib nucleotide hu ua a point kev hloov . Frameshiftmutations tshwm sim los ntawm kev ntxiv lossis tshem tawm ntawm singlenucleotide. Vim yog kev ntxiv lossis tshem tawm, kev nyeem ntawv ntawm mRNA hloov pauv thiab ua rau kom tiav txawv protein ntau.
Tsis tas li ntawd, qhov xwm txheej twg tshwm sim los ntawm kev hloov pauv hloov pauv? Tab sis, kev ntxig thiab tshem tawm ua rau muaj kev hloov pauv ntawm qhov ntev ntawm cov noob, uas ua rau muaj kev hloov pauv hauv codon nyeem ntawv. A frameshift kev hloov tshwm sim thaum cov protein ntau hloov pauv vim yog qhov ntxig lossis tshem tawm. Tus kab mob Tay-Sachs yog tib neeg kev puas siab puas ntsws tshwm sim los ntawm a frameshiftmutation.
Tsis tas li ntawd, dab tsi yog qhov kev hloov pauv quizlet?
Cov ntsiab lus hauv pawg no (27) Kev hloov pauv . kev hloov pauv hauv cov khoom siv caj ces ntawm acell; ua los ntawm qhov yuam kev thaum lub sij hawm DNA replication. Gene Kev hloov pauv . hloov mus rau ib lub noob. Taw tes Kev hloov pauv - koom nrog kev hloov pauv hauv ib lossis ob peb nucleotides / hauv paus.
Puas yog kev hloov pauv hloov pauv hloov pauv?
Frameshift kev hloov pauv yog insertions los yog deletions nyob rau hauv lub genome uas tsis nyob rau hauv ntau ntawm peb nucleotides. Frameshift kev hloov pauv tsis suav nrog hloov qhov twg ib tug nucleotide hloov lwm tus. Hauv kev hloov pauv , polypeptide tsuas yog hloov los ntawm ib qho aminoacid xwb.

Yuav ua li cas koj nrhiav tau qhov sib npaug ntawm ib kab uas muab ib tug point thiab ib tug parallel kab?
Qhov sib npaug ntawm kab hauv daim ntawv nqes hav-intercept yog y = 2x + 5. Qhov nqes hav ntawm parallelline yog tib yam: m = 2. Yog li, qhov sib npaug ntawm kab sib npaug yog y = 2x + a. Txhawm rau nrhiav ib qho, peb siv qhov tseeb tias kab yuav tsum dhau los ntawm qhov muab: 5 = (2) ⋅ (− 3) + a

Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
