Through a statistical scan we suggest the process of drawing a pattern with the purpose of constructing a choice. The pattern values are to be considered as the values of a random variable outlined on a few meas­ urable house, and the choices made are to be services of this random variable. even supposing the roots of this concept of statistical test expand again approximately 2 hundred years, the formal therapy, which contains an outline of the potential selection approaches and a wakeful try to keep watch over mistakes, is of even more fresh foundation.

Either way the exposed single chains now attract primed nucleotide units in a complementary fashion. These units link together on each of the single chains turning them into new stretches of double chain. Unwinding and chain-making continues, and the final outcome is a pair of identical double chains in place of the original one. ) The forces that are responsible for choosing the new units, so that they match up, are secondary forces of the kind that we discussed briefly in the last chapter. While the covalent bonds that hold the units together through their connector pieces are formed (more or less) once and for all, the forces between the letter pieces - the 'plug-socket' pairing forces - are much less emphatic.

It is similar to the confidence we have in our everyday perceptions and rests on a similar base. We are pretty sure the chair is real. If need be we can become more and more sure that it is not a deception or a hallucination by taking in new data - preferably of diverse kinds. We look at the chair from a new angle, we lift it up, kick it, sit on it. As the new data continue to check out as 'chair-like', vestiges of doubt are soon removed. Scientific perceptions - concepts, insights - cannot literally be kicked to see if they are real; but we do something similar when we check out an idea.

The carpenter must first choose and carefully align the appropriate pieces of wood before the decisive act of pinning or glueing them together. What do the messages mean? To a first approximation the messages in E. coli mean proteins - two or three thousand different kinds of protein molecule, each a machine with a more or less particular function. The purpose of most of the messages in E. coli (and that goes for some of our central messages too) is the direct specification of this molecular machinery.
