Sequencing and Analysis of the Hydra Genome
Chapman, Kirkness et al., Nature
An international research collaboration reports their sequencing and analysis of the Hydra magnipapillata genome, and compare it to the genomes of several other organisms. "The Hydra genome has been shaped by bursts of transposable element expansion, horizontal gene transfer, trans-splicing, and simplification of gene structure and gene content that parallel simplification of the Hydra life cycle," the authors write. They team suggests that comparisons of the Hydra genome to the reported sequences of other animals have helped them to elucidate the evolution of several of the organism's characteristics.
Researchers Develop Method for Distinguishing Ancient Human DNA from Modern Day Contaminants
January 04, 2010
German and Russian researchers used information from Neandertal sequences to distinguish ancient human DNA from modern day contaminants and applied this approach to sequence the mitochondrial genome from 30,000-year-old human remains.
