In 1981, american biochemist thomas cech discovered that certain rna molecules appear to act as enzymes, molecules that speed up, or catalyze, some reactions inside cells. Until this discovery biologists thought that all enzymes were proteins. Like other enzymes, these rna catalysts, called ribozymes, show great specificity with respect to the reactions they speed up.

Atoms, however, have fixed relative weights, called atomic weights, so the symbols often stand for one atomic weight of the element. Later investigations by the american biochemist julius axelrod, the swedish physiologist ulf von euler, and the british physician sir bernard katz demonstrated the role of specific chemicals in the transmission of nerve impulses. Gene chips also distinguish between active dnadna that is being transcribed to produce mrnaand inactive dna. The atomic weights (atomic wt. When they are called into action, these peptides are broken down into biologically active hormones and secreted into the blood to be circulated throughout the body. The implications can be significant: the amino acid sequence distinguishing normal hemoglobin from the altered form of hemoglobin responsible for sickle-cell anemia differs by only a single amino acid. As a reaction proceeds, the concentration of the reactants usually decreases as they are used up.
