Ancient gene

Researchers at UD use ancient gene to study virus biology

Researchers at the University of Delaware have discovered that an ancient gene — ribonucleotide reductase (RNR), which occurs in all cellular life — provides important biological insights into the characteristics of unknown viruses in the sea. (more…)

Of Mice and Men

*The genomes of 17 common strains of lab mice were sequenced to advance genetic studies of human diseases*

Scientists have sequenced the genomes (genetic codes) of 17 strains of common lab mice–an achievement that lays the groundwork for the identification of genes responsible for important traits, including diseases that afflict both mice and humans.

Mice represent the premier genetic model system for studying human diseases. What’s more, the 17 strains of mice included in this study are the most common strains used in lab studies of human diseases. By enabling scientists to list all DNA differences between the 17 strains, the new genome sequences will speed the identification of subsets of mutations and genes that contribute to disease.
