This statement is not entirely accurate. While an organism's genetic code, or DNA, remains largely constant throughout its lifetime, changes can occur due to mutations or other genetic mechanisms. Mutations can be caused by environmental factors or errors during cell division, leading to changes in the genetic code of an individual. Additionally, gene regulation and expression can also vary throughout an organism's lifetime, influencing traits and development. Overall, while an organism's genetic code is generally stable, changes can and do occur over time.
