Genomes:  Worming into genetic instability

Susan M. Rosenberg1 & P. J. Hastings1

A study of roundworms shows that genomic mutations occur surprisingly frequently, and that the kinds of changes involved differ from those predicted. Are genomes inherently less stable than previously suspected?

DNA carries the coded information that specifies the size, shape, body plan and many other basic characteristics of most organisms. To transmit these characteristics faithfully, DNA must pass from generation to generation with relatively few mutations.
