What does the recurring motif of the "DNA sequence" represent in GATTACA?

The recurring motif of the "DNA sequence" in GATTACA serves as a powerful representation of the interplay between genetics and the concept of identity. It illustrates how an individual's genetic makeup can define their traits, capabilities, and even their societal status. The film explores the limitations that society imposes based on genetic predispositions, highlighting conflicts between what one inherits from their parents (nature) and the individual choices they can make (nurture). The protagonist, Vincent, strives to transcend the genetic limitations that are placed upon him, symbolizing the struggle between predetermined fate and personal ambition. This motif emphasizes the complexities of identity formation, suggesting that while genetics can influence a person's life, it should not wholly determine their potential or worth.
