Ho latellana ha DNA ke eng?
Ho latellana ha DNA ke mokhoa oa ho khetholla tatellano ea acid ea nucleic <unk> tatellano ea li-nucleotide ho DNA. E akarelletsa mokhoa leha e le ofe kapa theknoloji e sebelisetsoang ho fumana tatellano ea metsoako e mene: adenine, guanine, cytosine le thymine. Ho hlaha ha mekhoa e potlakileng ea ho khetholla DNA ka tatellano ho potlakisitse haholo lipatlisiso le lintho tse sibolotsoeng tsa baeloji le tsa bongaka.  Tsebo ea tatellano ea DNA e fetohile ea bohlokoa bakeng sa lipatlisiso tsa motheo tsa baeloji, Merero ea Genographic ea DNA le libakeng tse ngata tse sebelisoang tse kang ho hlahloba meriana, biotechnology, biology ea forensiki, virology le systematics ea baeloji. Ho bapisa mekhahlelo ea DNA e phetseng hantle le e fetohileng ho ka khetholla maloetse a sa tšoaneng ho akarelletsa le kankere e sa tšoaneng, ho khetholla lethathamo la li-antibody,'me ho ka sebelisoa ho tataisa phekolo ea mokuli. Ho ba le mokhoa o potlakileng oa ho hlophisa DNA ho lumella tlhokomelo ea bongaka e potlakileng le e etselitsoeng motho ka mong hore e fanoe, le hore lintho tse phelang tse eketsehileng li khetholloe le ho thathamisoa.  Lebelo le potlakileng la ho hlophisa le fumanoeng ka theknoloji ea morao-rao ea ho hlophisa DNA le thusitse haholo ho hlophisa likarolo tse feletseng tsa DNA, kapa liphatsa tsa lefutso, tsa mefuta le mefuta e mengata ea lintho tse phelang, ho kopanyelletsa le liphatsa tsa lefutso tsa motho le likarolo tse ling tse feletseng tsa DNA tsa mefuta e mengata ea liphoofolo, limela le likokoana-hloko.  Litsamaiso tsa pele tsa DNA li ile tsa fumanoa mathoasong a bo-1970 ke bafuputsi ba thuto ba sebelisang mekhoa e boima e thehiloeng ho chromatography ea mahlakore a mabeli. Ka mor'a hore ho hlahisoe mekhoa ea ho hlophisa e thehiloeng ho fluorescence e nang le sequencer ea DNA, ho hlophisa DNA ho se ho le bonolo ebile ho potlakile haholo. [
