Introduction to Bioinformatics
Bioinformatics is an interdisciplinary field that
combines biology, computer science, mathematics, and statistics to analyze and
interpret biological data. It plays a crucial role in modern biology and
zoology, enabling researchers to manage and make sense of the vast amounts of
data generated by genomic, proteomic, and other biological studies.
Definition of Bioinformatics
Bioinformatics can be defined as the use of
computational tools and techniques to analyze biological data, particularly at
the molecular level. It encompasses data storage, retrieval, and analysis,
focusing on patterns and relationships within biological datasets.
Applications of Bioinformatics
