What does Irene mean when she says "I had you sequenced"?

When Irene says "I had you sequenced," she is referring to a DNA test. In the context of the film "GATTACA," sequencing typically involves analyzing an individual's genetic material to determine their DNA profile. This process reveals a wealth of information about a person's genetic predispositions, health risks, and overall suitability for various societal roles. It suggests that she has obtained detailed genetic data about the person in question, which is significant in the dystopian world of GATTACA where genetics play a critical role in determining one's social status and opportunities. This statement underscores the central theme of the film related to genetic engineering and determinism, highlighting how DNA analysis intersects with personal identity and societal expectations.
