According to van der Waals radii (or molecular surface rendering), atom of residue 148 is most likely hydrogen-bonded to the phosphodiester of dG4 in Chain A, which means this noncovalent interaction is pH-.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
