Su'aalaha ku saabsan maquette-kan 3D
Qaab noocee ah ayuu molecule-ka DNA-hu leeyahay?
DNA guud ahaan waxay leedahay qaab laba-helix ah: laba xargood oo isku duuban, sida sullaan la qallajiyay. Xadhig kastaa wuxuu leeyahay taxane ka kooban sonkorro iyo kooxo fosfeyt ah oo lagu lifaaqay saldhigyo (bases).
Saldhigyada (bases) kee ayaa isku lammaanaya DNA-ga?
Afarta saldhig ee DNA-hu waa adenine, thymine, cytosine, iyo guanine. Laba-helix-ka dhexdiisa, adenine wuxuu lammaanaa thymine, cytosine na wuxuu lammaanaa guanine. Lammaanahaasi waxay isku xirayaan labada xargood.
