Computational Biology is an interdisciplinary field that uses mathematical models, algorithms, and computational techniques to analyze and interpret biological data. It plays a crucial role in genomics, protein structure prediction, and understanding complex biological systems. Key areas include sequence alignment, systems biology, and bioinformatics, helping to uncover patterns in DNA, RNA, and protein sequences. Computational tools are used for drug design, personalized medicine, and understanding evolutionary processes. This field is essential for advancing our understanding of biology at a molecular level and has applications in healthcare, agriculture, and biotechnology.
