Hammond shows the crew a video that explains how Jurassic Park scientists acquired dinosaur DNA and cloned them. The video features Mr. DNA, a computerized DNA strand that explains what DNA is, illustrates its structure, and provides other details about it. This clip is an excellent introduction to DNA.
Hank explains that DNA stores our genetic instructions and illustrates how DNA is structured. He explains the parts of the Double Helix structure and uses a book to put into perspective just how many base pairs are tightly packed in each chromosome.
