Domain alignment in bioinformatics.

Bioinformatics is an interdisciplinary field that develops methods and software tools for understanding biological data. As an interdisciplinary field of science, bioinformatics combines computer science, statistics, mathematics, and engineering to analyze and interpret biological data. Bioinformatics is considered a part of computational biology.

History

The term "bioinformatics" was coined in the 1970s, but the field began to take shape in the 1980s with the advent of genome sequencing projects. The Human Genome Project, which began in 1990 and was completed in 2003, was a major milestone in the field.

Applications

Bioinformatics has a wide range of applications in various areas of biology and medicine.
