Before revision:  The only serious limitation of this type of translation modeling is in that it does not take into account possible interactions between ribosomes. The latter might lead to more complex phenomena which can be taken into account in simulatory models of the detailed representation of translation at the cost of more difficult analytical analysis of the model .
After revision:  The only serious limitation of this type of translation modeling is in that it does not take into account various phenomena such as the interaction between translating ribosomes or regulation of translation by microRNA. The model can be used as a building block (translation module) for more complex models of cellular processes .
