Spinning DNA as fast as a jet engine where it climbs along the double helix, unzipping it at its nose and re-zipping it at its tail, helicase catalyzes the construction of mRNA, copying the code as it passes along. Gathering free RNA nucleotides through a special induction tunnel, it matches them, and then shunts the forming mRNA strand out its side. It must start and stop at precise locations controlled by many factors releasing its products and reassembling somewhere else to do another job. Therefore, helicase is not only a precise and complicated catalyst, but it must be responsive to various work controls; there is more intelligence in this than we know of, and this is a growing field of molecular experimental research. Helicase is not a random grouping of proteins, nor are the proteins that compose it a random grouping of amino acids. Again, this is a precision machine far outside the realm of mathematical random probability. Added to its own complexity, the fact that its own blue prints are some of the products it makes as it slides precisely along the complex DNA molecule, the complexity becomes irreducible, incapable of simplifying without destroying the whole purpose of the system. The number of sequential dependent operations in this system, its fabrication, maintenance, and reproduction, begins to look like the grains of sand upon the sea shores.
