Of Mice and Men

Overall, mice and humans share virtually the same set of genes. Almost every gene found in one species so far has been found in a closely related form in the other. Of the approximately 4,000 genes that have been studied, less than 10 are found in one species but not in the other.

Both the mouse and human genomes contain about 3.1 billion base pairs (or chemical letters). Only about 5 percent of the sequence consists of protein-coding regions (genes)….
