Richard -- A good question! Note first that my statement is minimalist in order just to note its large difference from the other two common conceptions of information. Now, in order to see that the genetic system would come under this general usage of information as carrying meaning, we need to stipulate a 'system of interpretance' for whom genetic information would be meaningful. This we can assign to the cell. The cell enagages in measurements (semiosis) by relating to some object (concentration of molecules, or numbers of impacts with some kind of molecule. Its reaction to this information is to generate interpretants (production of RNA nucleic acid entities), which induce a sign (finished mRNA), which acts to feedback on the genetic system by producing more RNA nucleic acid entities. The triadic relations between Object, Interpretants and the Sign is formally like perception. The meaning here emerges during the triadic relations of perception. It is created by the cell. The difference that makes a difference to the cell is some marked increase in some molecular species that it can detect as requiring a response. If I were a cell biologist or 'systems bologist' I probably could make this reading more detailed.
