Complete the complementary base pair for the following DNA strands

According to Chargaff's rule, the concentration of A to T is always equal, and the concentration of G to C is equal. This means if you know the amount of one base, you can figure out the other!

What would be the correct concentrations if you have 35% A and 15% G?

• 40% T and 20% G

• 35% T and 15% G

• 40% T and 15% G

• 35% T and 20% G
