Sequencing genetic material is now common practice. The general population have become consumers of this information but without an understanding of the biological processes that render sequencing data useful. The interpretation of genetic sequence depends on an appreciation of the basics of genetics and the limits of such data. This book provides the background necessary to understand, interpret, and apply sequencing information to real- world problems. Replication of genetic material, the structure of DNA, typing methods, and forensic applications are all discussed in this useful primer.
