Nyob rau hauv ib txoj kab los yog capillary ntawm a ua ke tshuab mus sib tov ntawm DNA los ntawm tag nrho plaub pawg. Vim hais tias me me molecules txav los ntawm cov gel sai dua, cov DNA daim tuaj los ntawm cov gel nyob rau hauv qhov kev txiav txim ntawm loj-txhua daim ib lub hauv paus ntev dua qhov kawg.
Ua li no, DNA sequencing siv sijhawm ntev npaum li cas?

Kuj Paub, 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.
Hauv qhov no, dab tsi yog gene sequencing piav qhia?
GENOME SEQUENCING . Genome sequence yog xam tawm qhov kev txiav txim ntawm DNA nucleotides, los yog hauv paus, hauv a genome -Qhov kev txiav txim ntawm As, Cs, Gs, thiab Ts uas ua rau lub cev DNA . Ntau npaum li koj lub qhov muag scans a ib ntus ntawm cov ntawv nyeem ib kab lus, cov tshuab no "nyeem" a ib ntus ntawm DNA hauv paus.
Dab tsi yog sequencing in English?
Sequencing hais txog kev txheeb xyuas cov ntsiab lus ntawm ib zaj dab neeg - pib, nruab nrab, thiab xaus - thiab tseem muaj peev xwm rov hais dua cov xwm txheej hauv cov ntawv sau hauv qhov kev txiav txim uas lawv tshwm sim.

Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Yuav ua li cas yog vim li cas vim li cas lub epigenome hloov?
Kev ua neej nyob thiab ib puag ncig (xws li kev haus luam yeeb, noj zaub mov thiab kab mob sib kis) tuaj yeem ua rau tus neeg muaj kev ntxhov siab uas ua rau muaj tshuaj lom neeg. Cov lus teb no, dhau los, feem ntau ua rau muaj kev hloov pauv hauv epigenome, qee qhov tuaj yeem ua rau puas tsuaj
Alu TPA sequence yog dab tsi?
Chromosome, txhawm rau nrhiav qhov ntxig ntawm DNA luv luv, hu ua Alu, nyob rau hauv. Cov ntaub so ntswg plasminogen activator (TPA) noob. Alu cov ntsiab lus raug cais raws li SINEs, lossis luv INterspersed Elements
Yuav ua li cas koj nrhiav tau lub sij hawm tom ntej nyob rau hauv ib tug quadratic sequence?
Sau lub nth lub sij hawm ntawm no quadratic naj npawb sequence. Kauj Ruam 1: Paub meej tias qhov sib lawv liag yog quadratic. Qhov no yog ua los ntawm kev nrhiav qhov sib txawv thib ob. Kauj Ruam 2: Yog tias koj faib qhov sib txawv thib ob los ntawm 2, koj yuav tau txais tus nqi ntawm a
Yuav ua li cas cov amino acid sequence txiav txim cov yam ntxwv ntawm ib tug kab mob?
Cov noob yog ib ntu ntawm DNA molecule uas txiav txim siab cov qauv ntawm polypeptides (proteins) thiab yog li qhov tshwj xeeb. Qhov sib lawv liag ntawm nucleotides hauv DNA txiav txim qhov sib lawv liag ntawm cov amino acids hauv polypeptides, thiab yog li cov qauv ntawm cov proteins. Txhua tus uas yog lub luag haujlwm rau ib qho kev zoo
