Sanger sequencing yog ib txoj hauv kev zoo rau cov kev tshawb fawb txawv txawv thaum tag nrho cov qauv qis. Rau cov kev tshawb fawb sib txawv uas cov qauv lej siab, amplicon ua ke nrog NGS yog qhov ua tau zoo dua thiab muaj txiaj ntsig zoo.
Ib yam li ntawd, koj tuaj yeem nug, lub hom phiaj ntawm Sanger sequencing yog dab tsi?
Sanger sequencing yog cov txheej txheem ntawm kev xaiv kev koom ua ke ntawm cov saw-txiav Dideoxynucleotides los ntawm DNA polymerase thaum lub sij hawm hauv vitro DNA replication; nws yog txoj kev siv dav tshaj plaws rau kev tshawb nrhiav SNVs.
Kuj Paub, vim li cas ddNTPs siv hauv Sanger sequencing? Dideoxynucleotides yog chain-elongating inhibitors ntawm DNA polymerase, siv hauv Sanger txoj kev rau DNA sequence . Yog li, cov molecules tsim lub hauv paus ntawm Dideoxy saw-txiav txoj kev ntawm DNA sequence , uas tau tshaj tawm los ntawm Frederick Sanger thiab nws pab neeg nyob rau hauv 1977 raws li kev txuas ntxiv ntawm kev ua haujlwm dhau los.
Kuj nug, vim li cas NGS zoo dua Sanger?
Sanger sequencing tuaj yeem ua raws li ib feem ntawm ib lub sijhawm. Vim NGS siv cov hlwb uas tuaj yeem khi ntau lab ntawm DNA, NGS tuaj yeem nyeem tag nrho cov kab ke no tib lub sijhawm. Qhov no high-throughput feature ua rau nws raug nqi heev thaum sequencing ib tug loj npaum li cas ntawm DNA.
Koj xav tau dab tsi rau Sanger sequencing?
Cov khoom xyaw rau Sanger sequencing Lawv suav nrog: A DNA polymerase enzyme. Ib tug primer, uas yog ib tug luv luv daim ntawm ib leeg-stranded DNA uas khi rau lub template DNA thiab ua raws li "pib" rau cov polymerase. Plaub DNA nucleotides (dATP, dTTP, dCTP, dGTP)

Vim li cas peb thiaj li yuav tsum txo peb cov hneev taw ecological?
Raws li peb tam sim no tus nqi ntawm kev noj, peb tab tom nqus 157% ntawm cov khoom siv ntuj tsim nyob hauv ntiaj teb, txhais tau tias peb xav tau lub ntiaj teb thiab ib nrab los tswj peb cov hneev taw ecological. Txhawm rau khaws peb cov peev txheej ntxiv, nws tseem ceeb heev uas peb txo peb cov kev siv
Vim li cas peb thiaj siv GMOs?
Cov qoob loo. Genetically hloov cov qoob loo (GM qoob loo) yog cov noob hloov cov nroj tsuag uas siv rau hauv kev ua liaj ua teb. Thawj cov qoob loo tsim tau siv rau tsiaj lossis tib neeg cov zaub mov thiab muab kev tiv thaiv rau qee yam kab tsuag, kab mob, tej yam kev mob, spoilage los yog tshuaj kho mob (xws li tsis kam mus rau herbicide)
Vim li cas peb thiaj siv FIFO txoj kev?
Thawj-hauv, thawj-tshaj tawm (FIFO) cov nqi khoom muag tuaj yeem siv los txo cov nqi se thaum lub sijhawm nce nqi, vim tias cov khoom muag ntau dua ua haujlwm kom nce lub tuam txhab tus nqi ntawm cov khoom muag (COGS), txo nws cov nyiaj tau los ua ntej paj, se, depreciation and amortization (EBITDA), thiab yog li ntawd txo cov nqi
Dab tsi yog qhov txawv ntawm Sanger sequencing thiab tiam tom ntej sequencing?
Next-generation sequencing (NGS) technologies zoo ib yam. Qhov sib txawv tseem ceeb ntawm Sangersequencing thiab NGS yog sequencing ntim. Thaum txoj kev Sanger tsuas yog ua raws ib qho DNA ib ntus tib lub sijhawm, NGS yog qhov sib npaug loj heev, ua rau ntau lab tus kab mob ib txhij ib zaug
Vim li cas thiaj li yuav tsum tau ua kom huv PCR cov khoom ua ntej sequencing?
Kev txheeb xyuas cov khoom xav tau yog qhov tseem ceeb, uas suav nrog kev lees paub qhov tsis muaj cov khoom tsis muaj tshwj xeeb thiab primer dimers. Kev ntxuav ntawm cov tshuaj tiv thaiv sib tov kuj tseem tsim nyog los tshem tawm cov tsis muaj kev sib koom ua ke primers thiab dNTPs uas tuaj yeem cuam tshuam cov kev tshwm sim tom ntej thiab ua rau muaj qhov tsis tau nyeem
