Transposable elements and fitness of bacteria.
A stochastic model was designed to describe the evolution of bacterial cultures during 10,000 generations. It is based on a decreasing law for the generation of beneficial mutations as they become fixed in the genomes. Seven beneficial mutations on average were necessary to improve the relative fitness from 1.0 to 1.43 and the model was consistent with the population biology and the genetic dat...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولCompetition between transposable elements and mutator genes in bacteria.
Although both genotypes with elevated mutation rate (mutators) and mobilization of insertion sequence (IS) elements have substantial impact on genome diversification, their potential interactions are unknown. Moreover, the evolutionary forces driving gradual accumulation of these elements are unclear: Do these elements spread in an initially transposon-free bacterial genome as they enable rapid...
متن کاملIntergenic Transposable Elements Are Not Randomly Distributed in Bacteria
Insertion sequences (ISs) are mobile genetic elements in bacterial genomes. In general, intergenic IS elements are probably less deleterious for their hosts than intragenic ISs, simply because they have a lower likelihood of disrupting native genes. However, since promoters, Shine-Dalgarno sequences, and transcription factor binding sites are intergenic and upstream of genes, I hypothesized tha...
متن کاملTransposable elements in Drosophila
Transposable elements (TEs) are mobile genetic elements that can mobilize within host genomes. As TEs comprise more than 40% of the human genome and are linked to numerous diseases, understanding their mechanisms of mobilization and regulation is important. Drosophila melanogaster is an ideal model organism for the study of eukaryotic TEs as its genome contains a diverse array of active TEs. TE...
