  We analyze the quantum dynamics of the Friedmann-Robertson-Walker Universe in
the context of a Generalized Uncertainty Principle. Since the isotropic
Universe dynamics resembles that of a one-dimensional particle, we quantize it
with the commutation relations associated to an extended formulation of the
Heisenberg algebra. The evolution of the system is described in terms of a
massless scalar field taken as a relational time. We construct suitable wave
packets and analyze their dynamics from a quasi-classical region to the initial
singularity. The appearance of a non singular dynamics comes out as far as the
behavior of the probability density is investigated. Furthermore, reliable
indications arise about the absence of a Big-Bounce, as predicted in recent
issues of Loop Quantum Cosmology.
