If it was DNA, you would have several thousand, million possibilities. ATGC are the only protein bases for DNA.

maybe, after ATCG is U.

Uracil is another nitrogenous base of a nucleic acid (RNA, not DNA)

There are only two possible combinations of these nitrogenous base:

AT and CG

Other than that, there is no possible combination as T cannot form hydrogen bond with C and G and A cannot form hydrogen bond with C and G
