Structural dynamics of eukaryotic chromosome evolution.
Large-scale genome sequencing is providing a comprehensive view of the complex evolutionary forces that have shaped the structure of eukaryotic chromosomes. Comparative sequence analyses reveal patterns of apparently random rearrangement interspersed with regions of extraordinarily rapid, localized genome evolution. Numerous subtle rearrangements near centromeres, telomeres, duplications, and i...
متن کاملChromosome Structure
Biology is divided into three great kingdoms: Eubacteria, Archaea and Eukaryota. Bacteria (Eubacteria and Archaea) are ubiquitous in the environment, and these small single-celled organisms growover an amazinglywide range of environmental conditions. For example, bacteria can grow at temperatures below freezing, and certainmembers of the archaea can grow at depths of over threemiles and at temp...
متن کاملStructure of eukaryotic RNA polymerases.
The eukaryotic RNA polymerases Pol I, Pol II, and Pol III are the central multiprotein machines that synthesize ribosomal, messenger, and transfer RNA, respectively. Here we provide a catalog of available structural information for these three enzymes. Most structural data have been accumulated for Pol II and its functional complexes. These studies have provided insights into many aspects of th...
متن کاملEukaryotic and prokaryotic gene structure
Genes consist of multiple sequence elements that together encode the functional product and regulate its expression. Despite their fundamental importance, there are few freely available diagrams of gene structure. Presented here are two figures that summarise the different structures found in eukaryotic and prokaryotic genes. Common gene structural elements are colour-coded by their function in...
متن کاملCircular permutation of a synthetic eukaryotic chromosome with the telomerator.
Chromosome engineering is a major focus in the fields of systems biology, genetics, synthetic biology, and the functional analysis of genomes. Here, we describe the "telomerator," a new synthetic biology device for use in Saccharomyces cerevisiae. The telomerator is designed to inducibly convert circular DNA molecules into mitotically stable, linear chromosomes replete with functional telomeres...
