This statement is false. While it is true that not all of the genetic material in an organism's genome codes for protein-coding genes, the non-coding regions still have important functions such as regulating gene expression and promoting DNA stability. Therefore, the proportion of functional genes varies between different genomes and cannot be generalized as only 25%.
