The Movie: Once dinosaur blood has been successfully extracted from the mosquito, all you have to do is throw in some frog DNA to suture up the gene gaps and you have a dinosaur genome. Dunk the embryo in an ostrich egg and wait for your very own raptor to hatch. Serve warmblooded.
Real Life: Even if we forgive the idea that enough dinosaur genetic material survived in liquid blood form, frog DNA would a terrible choice to use as a filler between its missing sequences. Even humans and dinosaurs share a stronger genetic link than frogs and dinosaurs. Filling gene gaps with froggy blueprints would result in one seriously creepy Frankenstein's monster that absolutely would not survive fertilization (and if it did, it would be a hideous thing to lay eyes on). Try bird DNA! What's that? They don't switch genders and so can't be used as a plot point? All right, you win this round, Spielberg.
