Menene wannan 'taswirar kwayoyin halitta' da ke cikin jikinmu?
A taƙaice dai, gwajin yatsu na DNA gwaji ne na sinadarai wanda ke bayyana yanayin halittar mutum ko wani abu mai rai. Domin fahimtar wannan, da farko muna buƙatar sanin menene DNA.
Kalmar DNA a takaice take nufin deoxyribonucleic acid . Ana samunta a cikin kowace ƙwayar halitta a jikinka. Ka yi tunaninta a matsayin tsarin rayuwarka gaba ɗaya.
Wannan sarkar DNA ta ƙunshi nau'ikan sinadarai guda 4. Muna kiran waɗannan 'tushe'. Waɗannan suna haɗuwa biyu-biyu don samar da 'tushe biyu'.

Bayan an ɗauki samfurin daga gare ku, za a aika shi zuwa dakin gwaje-gwaje. Ga abin da ke faruwa:
1. Keɓewar DNA: Da farko, ana ƙara sinadarai don raba DNA kawai daga ƙwayoyin da ke cikin samfurin ku. Sannan, DNA ɗin yana narkewa cikin ruwa.
2. Yanke DNA zuwa gunduwa-gunduwa: Na gaba, wani tsarin sinadarai ya yanke wadannan dogayen sarkokin DNA zuwa kananan gunduwa-gunduwa wadanda ke da tsari mai maimaitawa wanda yake da mahimmanci a gare mu.
3. Kwafi gutsuttsuran: Mataki na gaba shine yin miliyoyin kwafi na waɗannan ƙananan gutsuttsuran DNA, wanda hakan zai sa a gwada su cikin sauƙi.
