Why is the movie titled GATTACA?

The title "GATTACA" is derived from the symbols representing the four nucleotide bases of DNA: Guanine (G), Adenine (A), Thymine (T), and Cytosine (C). This scientific term is integral to the themes of the movie, which explores the implications of genetic engineering and the societal impacts of a world where individuals are defined and limited by their genetic makeup. DNA sequencing and manipulation play a pivotal role in the narrative, making the title a direct reference to the genetic components that underpin the film’s exploration of identity and destiny. The connection to DNA emphasizes the movie's focus on biotechnology and its potential consequences for humanity, reinforcing the central ideas about genetics and personal worth.
