Here's why:
* Electrophoresis separates DNA fragments based on their size. Smaller fragments travel farther through the gel than larger fragments.
* The pattern created by the DNA fragments on the gel is unique to each individual (with the exception of identical twins). This pattern reflects the variations in the lengths of the DNA fragments, which are determined by the individual's specific DNA sequence.
* The pattern can be compared to other DNA profiles to determine if individuals are related or to identify suspects in criminal investigations.
Therefore, the resulting pattern is a fingerprint or profile that uniquely identifies an individual's DNA.
