The Chromosome Complement

  • Bernard John
  • Kenneth R. Lewis
Part of the Protoplasmatologia book series (PROTOPLASMATOL., volume 6 / A)


Biological systems express and reveal their specificity in different ways and at different levels. This specificity may be manifest in the choosing of a mate or a molecule and in the compatibility of a graft or a pollen grain. It is seen also in nutritional requirement and excretion product, in disease resistance and host range, in ecological preference and geographical distribution. It is expressed in chromosome pairing and the clotting of blood, in gametic fusion and in mating-call. All these properties express the distinctiveness of living systems and must ultimately rest on the shapes and surfaces of the macromolecules which contribute to their organisation. These chemical contours, in turn, are determined by the kind, the order and the degree of polymerisation of the monomer components.
