At this point ( the late 1970s and early 1980s ) little was known about the genetic and molecular mechanisms by which multicellular organisms develop from single cells to morphologically complex forms during embryogenesis.

At his full strength and power, Gambit can control all aspects of kinetic energy down even to the molecular level, allowing him to manipulate the potency of his bio-kinetic energy to burn, cause molecular discomfort, incinerate, create timed detonations ( and manipulate the potency of the energy release ), fire energy blasts, defy gravity, heal wounds, charge objects within his line of sight without contact, and effectively exist as an energy being.

At a molecular level, Na < sup >+</ sup > ions stabilize amino acid binding at the substrate site and also hold the transporter in an outward-open conformation that allows substrate binding.

At the molecular level this is associated with overexpression of heat shock and erythrocyte binding surface proteins with the reduced expression of a cell-cycle regulator and a DNA biosynthesis protein.
