It's interesting that the name 'Gattaca' is spelled using only the letters which stand for the four nucleotide bases which comprise DNA: guanine, adenine, thymine, and cytosine. The word GATTACA looks like a short sequence of DNA.
Trivia: The staircase in the house of the real Jerome Morrows is actually a resemblance of a DNA structure. Similar to Watson and Crick's model, except for the fact that the staircase has a right-handed turn. The DNA helix is a left-handed turn.
