If the base on a sequence on a separated dna strand is cgtagg, what will the base sequence on its complementary strand be?

It's complimentary DNA strand will be GCATCC. C always goes with G, and T always goes with A. If it's RNA then the complimentary strand would be GCAUCC. The only difference with RNA is that A matches with U. But C still matches with G, and if there's a T then it will match with A.
