A holographic presentation of DNA
DNA served as the information carrier, dictating a living being's physical attributes, encompassing its appearance, structure, shape and biological roles. As an illustration, the DNA within a Togruta population determined characteristics like the color of their lekku. The process of cloning, which involves generating an exact duplicate of a specified organism, necessitated the modification of that organism's DNA.
By comparing the DNA from a potential parent against the DNA of an individual thought to be their child, DNA could be utilized to ascertain parentage. Leia Organa, while contemplating whether to either confirm or deny before the Galactic Senate of the New Republic that Darth Vader was her father, reflected that, to her knowledge, no DNA samples had been discovered that were labeled either "Darth Vader" or "Anakin Skywalker."
