Unique tasks for ribosomal paralogues
JCB • VOLUME 179 • NUMBER 5 • 2007 808 Embryonic telomeres go long T elomeres go through a growth spurt early in embryonic development, as Lin Liu, David Keefe (University of South Florida, Tampa, FL), and colleagues report. The surge might help restore telomeres whittled down during oocytes’ long quiescence. Size is no issue for sperm, which maintain lengthy telomeres, and researchers assumed ...
متن کاملThe evolution of ribosomal DNA: divergent paralogues and phylogenetic implications.
Although nuclear ribosomal DNA (rDNA) repeats evolve together through concerted evolution, some genomes contain a considerable diversity of paralogous rDNA. This diversity includes not only multiple functional loci but also putative pseudogenes and recombinants. We examined the occurrence of divergent paralogues and recombinants in Gossypium, Nicotiana, Tripsacum, Winteraceae, and Zea ribosomal...
متن کاملA Unique Sensor Fusion System for Coordinate Measuring Machine Tasks
This paper describes a real-time hierarchical system that combines (fuses) data from vision and touch sensors to simplify and improve the operation of a coordinate measuring machine (CMM) used for dimensional inspection tasks. Our emphasis is on sensory processing techniques that can aid CMM applications rather than on the analysis of CMM performance measurements. Our system consists of sensory...
متن کاملAn ancient cluster of Wnt paralogues.
The recently completed sequences of the human and Drosophila genomes reveal an interesting conserved arrangement of a group of Wnt genes1. There are seven Wnt family members in Drosophila and 19 in the human genome. I aligned their protein sequences using the ClustalW program (shown on http://www.stanford.edu/ ~rnusse/genealigns/wntalign.html). The alignment confirmed an earlier phylogenic anal...
متن کاملA unique continuous solution for the Bagley-Torvik equation
In this paper the Bagley-Torvik equation as a prototype fractional differential equation with two derivatives is investigated by means of homotopy perturbation method. The results reveal that the present method is very effective and accurate.
