Schaeken, Joke J.F.A. van Vugt and Colin Logie Preface Point mutation is a vast subject that could not be captured in a set of fifteen vignettes. This book therefore reflects the interest of its authors, who are, for the most part, medically oriented scientists from all over the world, from Latin America to Russia and from Africa to Asia. A diverse array of research fields are broached, with an effort to bring the reader up to date with the knowledge amassed since the year 2000. After an introductory chapter on point mutation, current theory is expounded in two chapters on human point mutation. This is followed by five chapters on point mutation in viral genomes, going from adaptation of HIV to current therapies to antiviral vaccination and point mutation. Next, current trends in our knowledge of bacterial adaptation to quinolone antibiotics is described. This is followed by point mutagenesis in eukaryotic genomes, going from drug resistance in malaria to the nefarious effects of cigarette smoking. Finally, two contemporary synthetic point mutagenesis methodologies are described.

Microsatellite markers exhibit mutation rates that exceed the average mutation rates by two orders of magnitude In this work we shall put under scrutiny whether the nucleotide replacement process and the replication slippage mechanism produce comparable densities of mutational changes 1.4 The distribution of mutations along the chromosomes Since stochasticity is an essential component of the mutational processes... affected by an OXPHOS defect due to nuclear or mtDNA mutations were observed Patients with nuclear mutations became symptomatic at a young age, and had a severe clinical course Patients with mtDNA mutations showed a wider clinical spectrum of age at onset and severity Reported differences are of importance regarding the choice of type of genome in further studies of affected patients 2.2 Point mutations... with widely varying base composition exhibit uniformity of transition mutation rate both within and among mammalian lineages, with no relationship to intrachromosomal or interchromosomal effects This points to similarity in point mutation processes in genomic regions with substantially different GCcontent biases Knowledge of the mutational transition/transversion rate bias also allows a prediction... range of species by postulating that the production of intracellular ROS is the major determinant of life span Intracellular ROS are primarily generated by the mitochondrial respiratory chain and thus constitute a prime target for oxidative damage According to this theory, mtDNA mutations caused by ROS accumulate within the cell, leading to impaired respiratory chain proteins, thereby generating more... are encoded by both nuclear and mitochondrial genes Therefore, Rubio-Gozalbo et al (2000) examined whether there are clinical differences in patients suffering from OXPHOS defects caused by nuclear or mtDNA mutations 16 families with >=2 two siblings bearing a genetically established OXPHOS deficiency were studied, in four families due to a nuclear gene mutation and twelve due to a mtDNA mutation Differences .
