Hi Evgenii,
Any biological activity involves many chemical reactions that produce intermediate results, These reactions involve molecules whose structure are coded in DNA, transceribed and build by RNA . The produced protein respond to some need of the bacteria as a result of an internal or external event. Perhaps some food has been engulfed in the citoplasma and there is need for protein breaking enzimes. If you see the sequence of reactions in a piece of paper, it has the form of an algoritm. It does nor matter if it is executed in paralell, and several steps are executed at different times in different locations, but this does not change the algorithmic nature of the process, with the memorized set of instructions, the input the execution machinery and the output produced.
