TīmeklisA replicação do DNA corresponde à duplicação do material genético, pois o DNA faz uma cópia de si mesmo. As duas fitas que constituem a molécula se separam e orientam a formação de cadeias complementares que se unirão a elas. O ciclo celular pode ser dividido em dois momentos: interfase e divisão celular, por exemplo, a mitose. TīmeklisDNA replication is semi-conservative. This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with …
