Waa maxay isku xigxiga DNA?
Xisaabinta DNA-da waa habka lagu ogaanayo taxanaha nucleic acid <unk> amarka nucleotides ee DNA. Waxay ka kooban tahay hab kasta ama tiknoolajiyad kasta oo loo isticmaalo in lagu ogaado sida ay u kala horeeyaan afarta asaas: adenine, guanine, cytosine, iyo thymine. Soo bixitaanka hababka degdegga ah ee loo yaqaano DNA-da ayaa si weyn u dardar geliyey cilmi-baarista iyo helitaanka cilmiga bayoolajiyada iyo caafimaadka.  Aqoonta taxanaha DNA waxay noqotay mid lama huraan u ah cilmi baarista bayoolajiga aasaasiga ah, Mashaariicda DNA Genographic iyo meelo badan oo la adeegsado sida ogaanshaha caafimaadka, bayoolajiga, bayoolajiga sharciga, fayraska iyo nidaamka bayoolajiga. Isbarbar dhiga taxanaha DNA-da ee caafimaad qabta iyo kuwa isbeddelay ayaa lagu ogaan karaa cudurro kala duwan oo ay ku jiraan kansarro kala duwan, lagu tilmaami karaa sheyga antibody-ka, waxaana loo isticmaali karaa in lagu hago daaweynta bukaanka. Qaab dhakhso ah oo loo kala saari karo DNA-da ayaa u sahlaysa in si dhakhso ah loo helo daryeel caafimaad oo shakhsi ahaaneed, iyo in la aqoonsado oo la qoro noolaha badan.  Xawaaraha degdegga ah ee taxanaha ee lagu gaadhay tiknoolajiyada taxanaha DNA-da casriga ah ayaa wax ku ool u ahaa taxanaha taxanaha DNA-da oo dhameystiran, ama genomes, noocyo badan iyo noocyo kala duwan oo nolosha ah, oo ay ku jiraan hiddo-wadaha aadanaha iyo taxanaha kale ee DNA-da oo dhameystiran ee xayawaan badan, dhir, iyo noocyada microbes.  Tijaabooyinkii ugu horreeyay ee DNA waxaa soo saaray horraantii 1970-yadii cilmi-baarayaasha tacliinta sare iyagoo adeegsanaya habab adag oo ku saleysan laba-cabbir oo chromatography ah. Ka dib markii la soo saaray hababka taxanaha ee ku saleysan fluorescence oo leh taxanaha DNA, taxanaha DNA wuxuu noqday mid sahlan oo amarrada baaxadda ka dhakhso badan.
