}}</ref> Transkripsi adalah bagian dari rangkaian [[ekspresi genetik]]. Pengertian asli "transkripsi" adalah alih aksara atau penyalinan. Di sini, yang dimaksud adalah mengubah "teks" DNA menjadi RNA. Sebenarnya, yang berubah hanyalah [[basa nitrogen]] [[timina]] di DNA yang pada RNA digantikan oleh [[urasil]].
▲== proses ==
Transkripsi berlangsung di dalam [[inti sel]] atau di dalam matriks [[mitokondria]] dan [[plastida]]. Transkripsi dapat dipicu oleh rangsangan dari luar maupun tanpa rangsangan. Pada proses tanpa rangsangan, transkripsi berlangsung terus-menerus ([[gen]]-gennya disebut [[gen|gen konstitutif]] atau "gen pengurus rumah", ''house-keeping genes''). Sementara itu, gen yang memerlukan rangsangan biasanya gen yang hanya diproduksi sewaktu-waktu; gennya disebut [[gen|gen regulatorik]] karena biasanya mengatur mekanisme khusus. Rangsangan akan mengaktifkan bagian [[promoter inti]],<ref>{{en}}{{cite book
