Ho kopanya DNA ka tatellano ke eng?
Ho bioinformatics, ho kopanya tatellano ho bolela ho hokahanya le ho kopanya likhechana tsa tatellano e telele ea DNA e le ho aha bocha tatellano ea mantlha. Sena se hlokahala kaha theknoloji ea ho hlophisa DNA e ka 'na ea se ke ea khona ho 'bala' liphatsa tsa lefutso kaofela ka nako e le 'ngoe, empa e bala likotoana tse nyenyane tse pakeng tsa 20 le 30,000 tsa li-base, ho itšetlehile ka theknoloji e sebelisitsoeng. Ka tloaelo, likhechana tse khutšoanyane (tse baloang) li bakoa ke ho latellana ha DNA ea liphatsa tsa lefutso, kapa liphatsa tsa lefutso (ESTs).  Bothata ba ho bokella tatellano bo ka bapisoa le ho nka likopi tse ngata tsa buka, ho fetisa e' ngoe le e' ngoe ea tsona ka mochine o senyang ka sekontiri se fapaneng, le ho kopanya mongolo oa buka ka ho sheba feela likotoana tse senngoeng. Ntle le bothata bo totobetseng ba mosebetsi ona, ho na le litaba tse ling tse eketsehileng tse sebetsang: ea pele e ka 'na ea e-ba le lirapa tse ngata tse phetoang,' me likotoana tse ling li ka' na tsa fetoloa ha li ntse li khaoloa hore li be le liphoso tsa ho ngola. Likarolo tse tsoang bukeng e 'ngoe le tsona li ka' na tsa eketsoa,' me likarolo tse ling li ka' na tsa se ke tsa tsejoa ka ho feletseng.
