Practical Bioinformaticsis specifically designed for biology majors, with a heavy emphasis on the steps required to perform bioinformatics analysis to answer biological questions. It is written for courses that have a practical, hands-on element and contains many exercises (for example, database searches, protein analysis, data interpretation) to complement the straightforward and practical topics. The chapters are focused on DNA, RNA, and protein sequence analysis-frequently performed subsets of the field of bioinformatics-taking the reader through the commonly asked question what can I learn about this sequence?
