DNA is not the only thing needed to create a dinosaur. To clone a dinosaur, a mitochondrion will also be needed. Mitochondria are microscopic, membrane-enclosed organelles which produce the energy in eukaryotic cells, and are involved in many cellular activities, such as cell death, growth and signalling.

Creation of a dinosaur mitochondrionEdit

Mitochondria have their own DNA, which needs to be compatible with the DNA of the dinosaur nucleus. Mitochondria do not fossilize, and therefore we do not have a non-avian dinosaur mitochondria. However, it could be possible to create a dinosaur mitochondrion by comparing the mitochondrial DNA of a modern archosaur, such as birds and crocodilians.
