Careers that work with deoxyribonucleic acid (DNA) typically fall into two categories: research and manufacturing. Research jobs often focus on studies like how genetics impact vulnerability to diseases while manufacturing roles help to create samples for testing and examining how changes to DNA impact organisms. In this field, your responsibilities may include working to analyze samples from humans, animals, or plants, testing a variety of chemicals and medicines, or helping people understand their ancestry and biological relationships. DNA jobs also include adhering to a professional code of ethics and confidentiality. Many DNA-focused positions are found in the criminal justice field, such as victim identification, and the industry in which you work has a significant impact on how you use DNA on a day-to-day basis.
