Optimal Control of Evolutionary Dynamics [PDF]
arXiv, 2008 Elucidating the fitness measures optimized during the evolution of complex biological systems is a major challenge in evolutionary theory. We present experimental evidence and an analytical framework demonstrating how biochemical networks exploit optimal control strategies in their evolutionary dynamics.

Determination of absorption dose in chemical mutagenesis in plants.
PLoS ONE, 2019 Chemical mutagenesis is a useful tool for inducing mutations in plants. Seeds are often used as the material for chemical mutagenesis. The biological effect of a chemical mutagen on seeds is determined by absorption dose (the product of mutagen ...

Population and Mutagenesis or About Hardy and Weinberg One Methodical Mistake [PDF]
, 2013 The existing discrete form of the Hardy-Weinberg genetic law is applicable for a family tree. For population it is necessary to use a continuous time scale. The differential form of the Hardy-Weinberg law is offered.

Mechanisms of DNA damage, repair, and mutagenesis
Environmental and Molecular Mutagenesis, 2017 Living organisms are continuously exposed to a myriad of DNA damaging agents that can impact health and modulate disease‐states. However, robust DNA repair and damage‐bypass mechanisms faithfully protect the DNA by either removing or tolerating the ...

Mutagen specificity in barley for 1580 eceriferum mutants localized to 79 loci
, 2008 The paper presents 1580 mutants affecting the deposition of epicuticular waxes in cultivated barley and localized to 79 different cer loci. These mutations have been induced by various mutagens: ionizing radiations, organic chemicals, and the inorganic ...

Assessing Human Ribosomal DNA Variation and Its Association With Phenotypic Outcomes
BioEssays, Volume 47, Issue 4, April 2025.Genetic variation within the multi‐copy, multi‐locus ribosomal DNA (rDNA) can contribute to human complex trait variability. This variation takes the form of copy number, structural arrangement, and sequence differences. This review summarizes what is currently known about human rDNA variation, its causes, and its association with phenotypic outcomes ...

Solution of the Quasispecies Model for an Arbitrary Gene Network [PDF]
, 2004 In this paper, we study the equilibrium behavior of Eigen's quasispecies equations for an arbitrary gene network. We consider a genome consisting of $ N $ genes, so that each gene sequence $ \sigma $ may be written as $ \sigma = \sigma_1 \sigma_2 ... \sigma_N $.
