Molecular mechanisms driving Darwinian evolution
According to the Neodarwinian theory, biological evolution depends (1) on the availability of genetic variants, (2) on natural selection exerted on all available forms of life and (3) on geographical and reproductive isolation. The now available methodology of molecular genetics enables us to explore the molecular nature of genetic variation. It has become clear that many different molecular me...
متن کاملI-55: Molecular Imaging Overview
Molecular imaging is the noninvasive visualization of normal as well as abnormal cellular processes at a molecular or genetic level of function. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo). The discipline of molecular imaging evolved rapidly over the past decade through the integration of cell biology, molecular biology a...
متن کاملA Darwinian view of metabolism: molecular properties determine fitness.
Why do organisms make the types of chemicals that they do? Evolutionary theory tells us that individuals within populations will be subject to mutation and that some of those mutations will be enzyme variants that make new chemicals. A mutant making a novel chemical for that species will only survive in the population if the 'cost' of making the new chemical is outweighed by the benefits that r...
متن کاملArtificial Chemistry and Molecular Darwinian Evolution in Silico
A simplified model of Darwinian evolution at the molecular level is studied by applying the methods of artificial chemistry. A chemical reactor (chemostat) is composed of molecules that are represented by binary strings, where these strings are capable of a replication with a probability proportional to their fitness. Moreover, the process of replication is not fully precise, there may appear s...
متن کاملDarwinian aspects of molecular evolution at sublinear propagation rates.
Mean fitness is non-decreasing in the symmetry sector of the frequency trajectory followed in competitive replication at sublinear propagation rates (parabolic time course). This sector contains the pairwise symmetric distribution of species frequencies and its neighboring states, and represents at least half the possible states of an evolving sublinear system. States is the non-symmetry sector...
