Genetics, a cornerstone of life sciences, explores the structure, function, and inheritance of genes. With the advent of advanced computational technologies, genetics has expanded beyond biological boundaries and entered the realm of computer science. Concepts such as genetic algorithms, DNA computing, and bioinformatics are directly inspired by genetic principles. This paper examines the interdisciplinary relationship between genetics and computer science, emphasizing how genetic models inspire computational techniques and how computational tools accelerate genetic research. Applications range from medical diagnostics and drug design to artificial intelligence, optimization problems, and cybersecurity. This convergence of life science and computer science illustrates the potential for transformative innovations across multiple disciplines.
