It can be in our DNA as much as the browser on which you typed your comment is in the bits on your device's storage. That is true regardless of the fact that bits only code for binary 0|1 and 1s and 0s have nothing to do with displaying a DOM, taking user input, and sending it over a network. Equally, the fact that your device storage shares so many bit sequences with other devices does not imply it cannot have its own characteristics due to its own specific sequences. In any case though, the expression that something is "in one's DNA" is a common metonymy to express that it is the result of inheritable characteristics.
