  "textContent": "Genes undergo extensive editing through a process called alternative splicing, which greatly increases the size of the functional genome—the working portion of our DNA that helps make each person unique. Put simply, a single gene can be edited in different ways to produce multiple sets of instructions. This helps explain why humans differ so significantly from fruit flies and mice, despite having a similar number of genes.",
