The complementary strand to the DNA molecule g a t c c is c t a g g.

Here's why:

* Adenine (A) always pairs with Thymine (T)

* Guanine (G) always pairs with Cytosine (C)

So, following these rules:

* g pairs with c

* a pairs with t

* t pairs with a

* c pairs with g

* c pairs with g

Therefore, the complementary strand is c t a g g.
