On applicability of category theory to the description of ontogeny events

The possibility of application of the category-theoretical formalism to the description of the fundamental molecular events of ontogeny (transcription, translation and the protein combination formation) is studied. It is shown that a correspondence between these events and the well-known category operations, pull-back and push-out, can be established. The naturalness of application of the geometrical idea of fibration to the analyses of these events is demonstrated.
