Abubuwan al'ajabi na Nucleic Acid: Yadda DNA ke adana mahimman bayanan kwayoyin halitta na rayuwa

Nucleic acidabu ne da ba makawa a rayuwa. Yana iya adanawa da watsa ainihin halayen rayuwa da bayanan kwayoyin halitta ta hanyar bayanan jeri. Daga cikin su, DNA (deoxyribonucleic acid) shine mafi sanannunnucleic acidda wani muhimmin abu na binciken kwayoyin halitta na rayuwa. A matsayin kwayar halitta, kyakkyawan tsari da aikin DNA koyaushe yana haifar da bincike mai zurfi daga masana kimiyya.
