Kuyini ukulandelana kwe-DNA?
Ukulandelana kwe-DNA inqubo yokunquma ukulandelana kwe-nucleic acid <unk> ukuhleleka kwama-nucleotide ku-DNA. Ihlanganisa noma iyiphi indlela noma ubuchwepheshe obusetshenziselwa ukunquma ukuhleleka kwezakhi ezine: i - adenine, i - guanine, i - cytosine, ne - thymine. Ukuvela kwezindlela zokulandelela ngokushesha i - DNA kuye kwasheshisa kakhulu ukucwaninga nokuthola izinto eziphilayo nezokwelapha.  Ulwazi lwezinhlu ze-DNA luye lwadingeka kakhulu ekucwaningeni okuyisisekelo kwezinto eziphilayo, amaphrojekthi e-DNA Genographic nasemikhakheni eminingi esetshenziswayo njengokuxilongwa kwezokwelapha, i-biotechnology, i-forensic biology, i-virology kanye ne-biological systematics. Ukuqhathanisa ukulandelana kwe-DNA enempilo neguqukile kungathola izifo ezahlukene kuhlanganise nomdlavuza ohlukahlukene, kuchaza izakhi zomzimba ezilwa namagciwane, futhi kungasetshenziselwa ukuqondisa ukwelashwa kweziguli. Ukuba nendlela esheshayo yokulandelela uhlu lwe-DNA kuvumela ukunakekelwa kwezokwelapha okusheshayo nokuqondene nomuntu ngamunye, futhi kuvumela ukuba kuhlonzwe futhi kubhalwe izinhlobonhlobo eziningi zezinto eziphilayo.  Ijubane elisheshayo lokulandelela elifinyelelwa ngobuchwepheshe besimanje bokulandelela i-DNA liye laba nengxenye enkulu ekulandeleni ukulandelana kwe-DNA okuphelele, noma ama-genome, ezinhlobo eziningi nezinhlobo zokuphila, kuhlanganise ne-genome yomuntu nezinye ukulandelana kwe-DNA okuphelele kwezilwane eziningi, izitshalo, nezinhlobo zezinto ezincane eziphilayo.  Ukulandelana kwe-DNA kokuqala kwatholakala ekuqaleni kwawo-1970 ngabacwaningi bezemfundo besebenzisa izindlela eziyinkimbinkimbi ezisekelwe ku-chromatography enezinhlangothi ezimbili. Ngemuva kokuthuthukiswa kwezindlela zokulandelela ezisekelwe ku-fluorescence nge-DNA sequencer, ukulandelana kwe-DNA sekulula futhi kunemithetho yobukhulu ngokushesha. [
