Addicting

This game is very addicting I could play it for hours and not get bored. But the one problem I have is how do you get the black, white, and rainbow DNAs? I have some of the colored ones but I have no idea how to get the black, white, and rainbow ones and with out those u cant buy any of the other characters (besides the ones that cost flys).
