GENOMICS:
Sequence Tells Mouse, Human Genome Secrets
Elizabeth Pennisi
This week, researchers from around the world describe discoveries about the mouse genome that are providing insights into our own genetic code and making mice an even better biomedical research tool. An analysis of the sequence, published in the 5 December issue of Nature, is accompanied by five papers delving into the mouse's genetic characteristics and comparing them to those of humans. Some genes and other bits of sequence are similar across the board; elsewhere, there are intriguing differences.
