Hi-C raws li Genome Assembly

Hi-C yog ib txoj hauv kev tsim los ntes chromosome configuration los ntawm kev sib txuas kev soj ntsuam raws li kev sib cuam tshuam thiab kev sib tw siab.Qhov kev siv ntawm cov kev sib cuam tshuam no ntseeg tau tias muaj kev cuam tshuam tsis zoo nrog lub cev nyob deb ntawm chromosomes.Yog li, Hi-C cov ntaub ntawv tuaj yeem coj cov pawg, kev txiav txim thiab kev taw qhia ntawm cov kab ke sib dhos hauv cov txheej txheem genome thiab khi rau cov uas mus rau qee qhov chromosomes.Cov thev naus laus zis no txhawb nqa lub chromosome-theem genome los ua ke thaum tsis muaj cov pej xeem raws li daim ntawv qhia caj ces.Txhua lub genome xav tau Hi-C.
