Yog tias peb ua kom sov ib lub raj DNA yaj hauv dej, lub zog ntawm cov cua sov tuaj yeem rub ob txoj kab DNA sib nrug (muaj qhov kub tseem ceeb hu ua T m uas qhov no tshwm sim). Cov txheej txheem no hu ua ' denaturation'; thaum peb tau 'denatured' DNA, peb tau sov nws kom cais cov strands.
Kev sib cais ntawm DNA strands hu ua dab tsi?
Kev sib cais ntawm ob txoj hlua DNA tsim ib qho 'Y' zoo hu ua a replication 'fork'. Ob txoj hlua sib cais yuav ua raws li cov qauv los ua cov kab tshiab ntawm DNA.
DNA yog dab tsi thiab kev tshem tawm ntawm DNA?
Denaturing - thaum tus qauv ob-stranded DNA yog cua sov kom cais nws mus rau hauv ob qho tib si. Annealing - thaum qhov ntsuas kub qis kom ua kom cov DNA primers txuas mus rau cov qauv DNA. Txuas ntxiv - thaum qhov kub thiab txias tau nce thiab cov strand tshiab ntawm DNA yog tsim los ntawm Taq polymerase enzyme.
DNA txhais li cas?
the muaj peev xwm ntawm ob qhov sib ntxiv nucleic acids los ua kom haum rau hauv qhov kev taw qhia tawm tsam kom tso cai rau nucleotide hauv paus ntawm ib txoj hlua los tsim cov ntawv cog lus hydrogen nrog cov nucleotide hauv paus ntawm kev sib txuas ntxiv.
Dab tsi yog 5 kauj ruam hauv DNA replication?
Dab tsi yog 5 kauj ruam ntawm DNA replication nyob rau hauv kev txiav txim?
- Kauj Ruam 1: Kev Tsim Kho Cov Khaub Ncaws Rov Qab. Ua ntej DNA tuaj yeem rov ua dua, ob chav stranded molecule yuav tsum tau "unzipped" rau hauv ob qho tib si.xov.
- Kauj Ruam 2: Primer Binding. Txoj kev ua thawj coj yog qhov yooj yim tshaj plaws los rov ua dua.
- Kauj Ruam 3: Elongation.
- Kauj Ruam 4: Kev Txiav Txim.

Thaum lub sijhawm ntsuas qhov sib npaug ntawm qhov ntsuas cua sov yog nyob rau hauv kev sib cais?
Los ntawm txoj cai thib ob ntawm thermodynamics: Txoj cai thib ob ntawm thermodynamics hais tias qhov entropy ntawm ib qho cais qhov system yeej tsis txo qis, vim tias cov tshuab cais ib txwm hloov mus rau qhov sib npaug ntawm qhov ntsuas kub, lub xeev nrog siab kawg entropy.
Koj puas tuaj yeem khi hlua khi hlua?
Nrog rau kev ua kom sov thiab txias ua ntu zus, so kom txaus thiab noj zaub mov kom zoo, kev sib txuas yog ib txoj hauv kev zoo tshaj plaws los tiv thaiv lub ntsej muag. Kinesio daim kab xev yog tsim los rov qhia koj cov kab mob neuromuscular kom tiv thaiv kev raug mob.
Qhov twg yog qhov cuam tshuam ntawm kev sib cais cov paj huam rau hauv stanzas?
Stanzas muab cov kws sau paj huam nrog txoj hauv kev pom kev sib koom ua ke cov tswv yim hauv zaj paj huam, thiab ntawm muab qhov chaw ntawm cov tswv yim sib cais lossis ntu ntawm paj huam. Stanzas kuj pab rhuav cov paj huam mus rau hauv me me uas yooj yim nyeem thiab nkag siab.
