1. Base pairing rules
(DNA) - (RNA)
A pairs with U
T pairs with A
C pairs with G
G pairs with C

2. Directionality.
Unless otherwise specified, a single strand of DNA or mRNA is assumed to be written 5' first. To avoid confusion, the ends should ALWAYS be specified.
The complement matches up its 3' end where the given strand has its 5' end.
This is not a difficult concept.
