BadBiology: Gary Sinise's character is sitting at a computer monitor observing a short section (about two full twists) of DNA and exclaims that "This DNA looks human!" However, all DNA (regardless of the organism) has the same characteristic double-helix shape and is composed of the same nitrogenous bases. Furthermore, all mammals have about 90+% of their DNA in common. Thus, unless he sequenced the entire fragment and compared it to that known to be human, he has no scientific reason for drawing this conclusion.
