tom ntej no - tiam sequencing (NGS) thev naus laus zis zoo ib yam. Qhov tseem ceeb qhov sib txawv ntawm Sangersequencing thiab NGS yog ua ke ntim. Thaum lub Sanger txoj kev nkaus xwb ua ntu zus Ib qho DNA ib feem ntawm lub sijhawm, NGS yog qhov sib npaug loj heev, ua ke lab offragments ib txhij ib zaug.

Tsis tas li ntawd, yuav ua li cas lwm tiam neeg sequencing ua hauj lwm?

Lub hauv paus ntsiab lus qab Tom ntej no tsab xov xwm Sequence (NGS) zoo ib yam li Sanger ua ke , uas tso siab rau capillary electrophoresis. Cov genomic strand yog fragmented, thiab cov hauv paus hauv txhua qhov tawg tau txheeb xyuas los ntawm cov teeb liab tawm thaum cov fragments yog ligated tiv thaiv ib qho qauv strand.

Ib yam li ntawd, vim li cas NGS zoo dua Sanger? NGS yog pheej yig dua, nrawm dua, xav tau DNA tsawg dua thiab yog ntau raug thiab txhim khu kev qha tshaj Sanger ua ke. Cia peb saib qhov no ntau nyob ze. Rau Sanger sequencing, ib tug loj npaum li cas ntawm templateDNA yog xav tau rau txhua tus nyeem.

Ua li no, dab tsi yog txhais los ntawm cov tiam tom ntej sequencing?

Tom ntej no tsab xov xwm sequencing (NGS, NextGenSeq) yog ib new txoj kev rau ua ke genomes ntawm kev kub ceev thiab tus nqi qis. Nws tseem hu ua thib ob tiam (SGS) los yog loj heev thaum uas tig mus ua ke (MPS). Lub mitochondrial DNA tag nrho cov kab ke xeem los ntawm FTDNA kuj siv tiam tom ntej sequencing tshuab.

Yuav ua li cas lwm tiam neeg sequencing txawv ntawm ib txwm sequencing?

Conceptually, lub ntsiab txawv nruab nrab nextgeneration sequencing thiab ntau dua tsoos sequencing txoj kev xws li Sanger sequencing yog uas tiam tom ntej no sequencing muaj peev xwm ib ntus ntau ntau nucleotides hauv ib qho kev khiav, ib lub tswv yim peb xa mus rau highthroughput.
