Retroposition, a molecular mechanism generating new genes, helps the formation of retrogenes and new functions, contributing to the evolution of genomes. The completed genome sequence of Caenorhabditis sp. 5 presents an excellent opportunity to identify retrogenes within C. sp. 5. We identified a total of 43 retrogenes and their corresponding chimeric genes. Among these, 29 were found to be intact retrogenes and 14 to be retropseudogenes. Unexpectedly, a high number of retrogenes appear to be functional and possibly involved in catalysis. Also,...
