Griffith's Experiment: DNA and Heredity | Biology

How do we inherit traits from our parents? The short answer: DNA, or deoxyribonucleic acid. It's the hereditary material of all living organisms, and the history of its study is the subject of this video. We'll learn about the bacteriologist Frederick Griffith's landmark 1928 experiment, which revealed the existence of molecules that have the power to change the characteristics of an organism (the "transforming principle"), as well as follow-up experiments that confirmed DNA as the molecule of heredity.
