But his chosen host for the 2012 ceremonies, Eddie Murphy, soon left, too, and the role hasn't been satisfactorily filled since.
Some cuckoo species such as the new world brood-parasitic Tapera have evolved in such a way that female parasitic cuckoos are often very specialized in the mimicry in colors and pattern of the eggs of a few chosen host species (Payne et al. 2005).
In this way, a randomly chosen host is infected by the strain with higher R0, and the fate of this strain is followed in the population, until loss or fixation.
We performed simulations with the scale free topology in conditions where the infection starts in a single randomly chosen host.
Other aspects which need to be taken into account are the availability of precursors in the chosen host organism, substrate selectivity of chain assembling units, and compatibility of the parts of the machinery.
A widely used strategy is illustrated in Figure 1, where the chosen host cell is regarded as a 'cell factory' that can be used to produce the target protein.
