Link nucleotides to repair DNA! Pair the correct nucleotides (gray) with the proper bases on the moving DNA strands. To move to the next level, connect as many of the proper pairs as possible. You will cause mutations if you make incorrect pairs or allow unpaired bases to escape off the right side of your screen! If your mutation rate is too high, you cannot move to the next level.

Previous reviewers are silly

The game is cheap mindless fun like any other iPhone game. Match the base pairs as they pass by.

Previous reviewers are rating the game poorly for their own misunderstanding. First of all, the purple thing is a helicase, not RNA polymerase. It's true that transcription would result in a new RNA strand, but since you are matching thymines, not uracil, this is clearly replication. Another obvious sign this is replication is the fact that you are synthesizing both strands! If you're going to pick on the science of a cartoon iPhone game, you could start with the fact that you are synthesizing one strand in the 3' to 5' direction while the other is going 5'to 3'. There aren't any Okazaki fragments! But it doesn't matter, because it's a mindless cell phone game.

I give two stars because it does have the basic concept if what DNA does. That purple splash thing indicates RNA Polymerase. Which breaks the double helix into two as it does. Only RNA then takes place. More specifically mRNA. So therefore they should be using U (Uracil) instead of T (Thymine) to bond with A (Adenine) because RNA only contains Uracil and not Thymine. That is one of the main differences between DNA and RNA. So therefore I only give two stars.
