Bioinformatics is where computer science meets biology. It's a field where specialists use computer tools to make sense of complex biological data, especially genetic information. Think of it like being a detective who uses powerful computer programs to analyze DNA, proteins, and other biological information to help researchers discover new medicines, understand diseases, or improve crops. Some similar terms you might see are "computational biology" or "biological data science." People in this field create and use computer programs that help scientists organize, search through, and understand massive amounts of biological information that would be impossible to analyze by hand.
