Nucleoside analogues in which a group M replaces the natural base where M is (1) or (2) or (3), where each of X1, X2 and X3 are C or N, each of R6 and R7 is the same or different and each is H, NO2, CO, COR8, OR8, CN, O, CON(R8)2, COOR8, SO2R8, SO3R8, SR8, NHCHO, (CH2)n(R8)2, halogen, or a reporter moiety, each of R8 and R9 is H or hydrocarbyl or a reporter moiety, and n is 0-4. The analogues are substrates for polymerase and terminal transferase enzymes.
