Genome Evolution by Substitutions, Duplications and Deletions
Recently, detailed statistical analyses of sequenced genomes have provided support for the “evolution by duplication” theory proposed by S. Ohno. Based on Ohno’s theory, we suggest a parsimonious model consisting of substitutions, duplications, and deletions, and estimate the parameters of this model at various scales (word sizes) over several genomes. We conclude that deletions play as critica...
متن کاملMolecular evolution. Genome duplications: the stuff of evolution?
One of biology's greatest mysteries is how an organism as simple as a one-celled bacterium could give rise to something as complicated as a human. Thirty years ago, prominent geneticist Susumu Ohno of the City of Hope Hospital in Los Angeles put forth what many of his colleagues then considered an outrageous proposal: that great leaps in evolution --such as the transition from invertebrates to ...
متن کاملTransposable Element- driven Duplications during Hominoid Genome Evolution
p0001 Akin to any large texts in a natural language, hominoid genomes appear as palimpsests ofmorphemes, lexemes and other lexical modules, each with its own structure, distribution and fluctuating copy numbers (Zhou and Mishra, 2004; Thomas et al., 2004). Duplication appears to be one of the main mechanisms in shaping and reshaping this genomic architecture. Duplication occurs at multiple scal...
متن کاملAncient large-scale genome duplications: phylogenetic and linkage analyses shed light on chordate genome evolution.
Paralogous genes from several families were found in four human chromosome regions (4p16, 5q33-35, 8p12-21, and 10q24-26), suggesting that their common ancestral region underwent several rounds of large-scale duplication. Searches in the EMBL databases, followed by phylogenetic analyses, showed that cognates (orthologs) of human duplicated genes can be found in other vertebrates, including bony...
متن کاملgeopolitical genome and turkmenistan’s foreign policy evolution
extended abstract 1. introduction geopolitical genome is the potential of a country. as the genomics is the study of hundreds or perhaps thousands of simultaneous genetic reactions for identifying the main causes of disease and understanding the mechanism of an organism, the activation and extinguishing of the geopolitical genomes are those adopted policies based on the geographical and human p...
