Summary

Fundamental Concepts of Bioinformatics is the first textbook co-authored by a biologist and computer scientist that is specifically designed to make bioinformatics accessible to undergraduates and prepare them for more advanced work. Students learn what programs are available for analyzing data, how to understand the basic algorithms that underlie these programs, what bioinformatic research is like, and other basic concepts. Information flows easily from one topic to the next, with enough detail to support the major concepts without overwhelming students. Problems at the end of each chapter use real data to help students apply what they have learned so they know how to critically evaluate results from both a statistical and biological point of view.
