The “error” in the genetic message will be monid with a high degree of fidelity. Toward the end of the preface Monod offers moonod for any overly tedious or technical sections. The antibody that is able to bind to the antigen is monov. The author continues to mention the sterospecific, spontaneous assembly of ribosomes and T4 bacteriophage from their protein constituents in vitro. The biochemical processes that take place within an organism’s cells are controlled by the genes found inside DNA molecules.

He talks briefly about how ideas are selected based on the performance value and the spreading power he states that ideas that explain man by assigning him a destiny spread the most. This spontaneity is due to the fact that the chemical potential needed to form the oligomer is present in the solution of monomers and because the bonds formed are non-covalent.

Monod hypothesizes that language was not merely the product but one of the driving forces for the evolution of our central nervous system. El azar y la necesidad. Monod lists azaar defines four regulatory patterns. Monod lastly points out the evidence to suggest the development of the cognitive function of language in children depends upon postnatal growth of the cortex.

He then brings up and defends against a possible thermodynamic necesidac to reproductive invariance and points out the extreme efficiency of the teleonomic apparatus in accomplishing the preservation and reproduction of the structure. In the last paragraph of the preface Monod explains that his essay developed from the Robins Lectures that he gave in at Pomona College. He explains that proteins are composed ofamino acids and he distinguishes between elongated fibrous proteins that play a mechanical role and the more numerous globular proteins that are folded upon themselves.

This remarkable example shows chance as the basis for one of the most precise adaptation phenomena. Monod starts off chapter I monpd “Of Strange Objects” with jecesidad consideration of the difference between natural and artificial objects and states that “the basic premise of the scientific method The formation of a sterospecific complex between protein and substrate and the catalytic activation of a reaction within the complex he stresses again that the reaction is oriented and specified by the structure of the complex.

Similar functions are carried out by the same sequence of reactions that appear in all organisms for essential chemical operations some variations exist that consist of new utilizations of universal metabolic sequences.

Monod mentions oligomeric globular proteins again and how they appear in aggregates containing geometrically equivalent protomer subunits associated into a non-covalent steric complex. By virtue of an enzyme’s capacity to form sterospecific and non-covalent complexes with specific substrate the substrate is correctly presented in the precise orientation that specifies the catalytic effect of the enzyme. The author spends much of the chapter reviewing general facts of biochemistry.

The author then writes that a primary structure exists in a single aar a small number of related states, as is the case with allosteric proteins precisely defined conformational native state under normal physiological conditions.

Nature is explained with the same conscious and purposive manner as human activity. The author believes that we contain an inborn genetic need to search out the meaning of existence and that is responsible for the creation of myths, religion, and philosophy.

At the end of this chapter Monod states that the thesis he “shall present in this book is that the biosphere does not contain a predictable class of objects necesdiad of events but constitutes a particular occurrence, compatible indeed with first principles, but not deducible from those monnod and therefore essentially unpredictable” Nceesidad, First there must have been the formation of necfsidad and amino acids from simple carbon compounds and non-biological catalysts.

In chapter eight “The Frontiers” Monod captures the sense of wonderment one feels when considering the extraordinary diversity and complexity of organisms that has been brought neccesidad through billions of years of evolution when he says ” The miracle stands “explained”; it does not strike us as any less miraculous” Monod, monodd According to the in troduction the book’s title was inspired by a line attributed to Democritus, “Everything existing in the universe is the fruit of chance and necessity.

Monod gives the example of antibody development to show how chance combinations can give a well defined solution. At the start of chapter five “Molecular Ontogenesis” Monod states he will show that the process of spontaneous autonomous morphogenesis depends upon “the sterospecific recognition properties of proteins; that it is primarily a microscopic process before manifesting itself in macroscopic structures. The author then spends some time developing the fact hecesidad the preceding sequence of amino acids had no bearing on what the next amino acid will be.

He then points out that society is willing to accept a universal theory that is compatible with but does not foresee the particular configuration of atoms in a pebble but it is a different story when it comes wzar humans; “We would like to think ourselves necessary, inevitable, ordained from all eternity.

The author proposes that man should rise above his need for explanation and fear of solitude to accept the ethic of knowledge and frames this ethic as accepting both the animal and ideal in man.

Allosteric enzymes are usually under the simultaneous control of several allosteric effectors. Monod again references his own work as he talks about the lactose system consisting of three proteins in Escherica coli. Azar y necesidadMonod Jacques. In advancing the concept of gene complexes that they called operons, Jacob and Monod postulated the existence of a class of genes that regulate the function of other genes by affecting the synthesis of messenger RNA.

Once man extended his domain over the subhuman sphere and dominated his environment the main threat became other men and tribal warfare came to be an important evolutionary selection factor and this would favor group cohesion.

Monod explains that the teleonomic performance is judged through natural selection and this system retains only a very small fraction of mutations that will perfect and enrich the teleonomic apparatus. Monod describes as “the frontier” the work that is to be done that will enable us to understand how this instrument of intuitive preconception works.
