Seeing double: appreciating genetic redundancy.
Genetic and molecular analyses of developmental and physiological processes in numerous experimental systems have recently revealed unsuspected levels of complexity within genetic regulatory pathways. Perhaps most surprising is the result that loss-of-function mutations engineered within many regulatory genes have little or no effect on phenotype. Although the lack of phenotype suggests that th...
متن کاملSeeing beyond the double helix.
Epigenetics, or heritable changes not encoded in the DNA sequence, is a phenomenon important for an overall increase in the complexity of the genome without changes in gene sequence. Our complete genome is contained in each of our cells. Corneal cells are different than nerve cells due to a usage pattern of the genome that is maintained in a cellular memory of active or repressed genes. These “...
متن کاملThe trouble with seeing double
[1] The recently discovered phase transition for (Mg,Fe)SiO3 from perovskite to post-perovskite structure for pressure-temperature conditions in the lowermost mantle provides a plausible mechanism to explain a several percent shear velocity increase detected at the top of the D00 region in many regions. The phase transition has a large positive Clapeyron slope, and given the likely presence of ...
متن کاملDepictive Seeing and Double Content
A picture provides both configurational content concerning its design features, and recognitional content about its external subject. But how is this possible, since all that a viewer can actually see is the picture's own design? I argue that the most plausible explanation is that a picture's design has a dual function. It both encodes artistically relevant design content, and in turn that desi...
متن کاملGenetic Programming and Redundancy
The Genetic Programming optimization method (GP) elaborated by John Koza Koza, 1992] is a variant of Genetic Algorithms. The search space of the problem domain consists of computer programs represented as parse trees, and the crossover operator is realized by an exchange of subtrees. Empirical analyses show that large parts of those trees are never used or evaluated which means that these parts...
