Each rung is called a base pair because it consists of a pair of complementary chemicals called nitrogenous bases, attached end to end, either adenine (A) joined to thymine (T) or cytosine (C) attached to guanine...

Forced to concoct a drama, Glashow chooses as his story the constant intersections of theory and observation that led to the currently held beliefs about the structure of the atom. Just as in The Double Helix, another popular scientific work about an abstract theory, the scientist's own life takes on great importance. Interactions goes beyond simply imparting Glashow's knowledge of elementary particle physics (the realm of quarks, strangeness, charm and color)in an effort to present what he terms a "scientific autobiography...
