New insights into how genetic mutations arise

Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA.
The findings, reported in the Oct. 25 online edition of the Proceedings of the National Academy of Sciences (PNAS), may reveal new insights into how genetic mutations-tiny mistakes that occur during DNA replication-arise. The discovery was made in the laboratory of Eric Kool, a professor of chemistry at Stanford and co-author of the PNAS study. [Read more]
