DNA problem : dino-mosquito

Extract the dna from mosquitos ? Ok, why not I guess. But, how can we be sure the dna isn't the mosquito's one ? Don't you think there's a risk that the dnas mixed together ?

Well, it's time for consequences with this gigantic mosquito featuring claws, jaw and more wings which it got from the base genome (which is classified if not unknown).

About 2 meters long, this beast can reach an high of around 4 meters thanks to its very long legs, but it's also its weakness because of how fine they are even tho there are quite thick because of its size. But this is probably not enough to stop it from eating human blood which could probably kill someone in one time because of the quantity taken...
