  The predetermination, formation and maintenance of the primary morphogenetic
gradient (bicoid gradient) of the early Drosophila embryo involves many
interrelated processes. Here we focus on a system-biological analysis of the
processes of redistribution of bicoid mRNA in an early embryo. The results of a
quantitative analysis of experimental data, together with the results of their
dynamic modeling, substantiate the role of active transport in the
redistribution of bicoid mRNA.
