Small Design Decision – Teo Zi Lin

The small design decision I noticed in this movie is that the protagonist, Robert Daly, harvested DNA from saliva on a lollipop to steal Walton’s son’s DNA and create a clone for his virtual reality game.

In fact, collecting DNA from saliva is less expensive than DNA from blood, and saliva yields high quantity high-molecular weight DNA.
