title: [Evolutionary significance of the presence in mobile genetic elements of regulatory sites reacting to the environment. Regulatory site as a trigger].
abstract: A mathematical model of the Markov's process type describing the duplicative transposition of mobile genetic elements (MGE) has been developed. The possible role of MGE containing regulatory sites activated under unfavourable conditions has been considered. An analysis of the model has shown that there may be such regimes of environmental changes (sharp but random changes of the environment parameters) when sufficiently reliable survival of population is dependent on such MGE.
