In Jurassic Park, what type of animal DNA was used to fillin the gaps in the dinosaur DNA?

I guess, cows DNA.

In Jurassic Park, frog DNA was used to fill in the gaps in the dinosaur DNA. This was a plot device to allow the dinosaurs to potentially reproduce by changing sex, as some frog species can change sex in single-sex environments.

I’m not sure but I think the frog would be the answer because the rest don’t make sense

Uhm??🤔 I think a “frog” The frog is the closest thing to a lizard.
