If one strand of DNA has sequence ATCGTATG , the sequence in the...

Due to size and geometries of bases, the only possible pairing in $DNA$ are between $G$ (guanine)$and C$ (cytosine) through three $H$-bonds and between $A$ (adenine)$and T$ (thymine) through two $H$-bonds.

Thus, the complementary strand of $DNA$ will be
