Bioinformatics is a hybrid science that connects biological data with techniques for information storage, distribution, and analysis to support multiple areas of scientific research including biomedicine. Bioinformatics is dependent upon high-throughput data-generating experiments that consist of genomic sequence determinations and measurements of gene expression patterns. As an interdisciplinary science domain, bioinformatics utilizes and amalgamates biology, mathematics and statistics to analyse and interpret biological data. It encompasses biological studies that utilise computer programming as part of its methodology as well as a specific analysis pipeline that are used in the field of genomics. In the field of medicine especially, a number of important applications for bioinformatics have been discovered. This book provides comprehensive insights into the field of bioinformatics. It picks up individual branches and explains their need and contribution in the context of a growing economy. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of this subject.
