Stability of Rearrangement Measures in the Comparison of Genome Sequences
We present data-analytic and statistical tools for studying rates of rearrangement of whole genomes and to assess the stability of these methods with changes in the level of resolution of the genomic data. We construct datasets on the numbers of conserved syntenies and conserved segments shared by pairs of animal genomes at different levels of resolution. We fit these data to an evolutionary tr...
متن کاملHybridization and Genome Rearrangement
We infer post-hybridization rearrangements in a hybrid genome, given the gene orders on its chromosomes and some knowledge of the two parent genomes. We study this in two biologically and computationally different contexts, genome fusion and interspecific fertilization. Exact algorithms are furnished for some cases, and a heuristic based on the Hannenhalli-Pevzner theory for another.
متن کاملGenome Rearrangement and Planning
The genome rearrangement problem is to find the most economical explanation for observed differences between the gene orders of two genomes. Such an explanation is provided in terms of events that change the order of genes in a genome. We present a new approach to the genome rearrangement problem, according to which this problem is viewed as the problem of planning rearrangement events that tra...
متن کاملGenome Rearrangement
The difference between genome rearrangement theory and other approaches to comparative genomics, and indeed most other topics in computational molecular biology, is that it is not directly based on macromolecular sequences, either nucleic acids or proteins. Rather like classical genetics, its building blocks are genes, and the structures of interest are chromosomes, abstracted in terms of the l...
متن کاملGenome Rearrangement and Planning: Revisited
Evolutionary trees of species can be reconstructed by pairwise comparison of their entire genomes. Such a comparison can be quantified by determining the number of events that change the order of genes in a genome. Earlier Erdem and Tillier formulated the pairwise comparison of entire genomes as the problem of planning rearrangement events that transform one genome to the other. We reformulate ...
