DNA—deoxyribonucleic acid—is an essential biological molecule found in every living thing on the planet. Most people understand that DNA contains the information necessary to make living things and that it is passed down from parents to offspring. In my first course on DNA (DNA basics, Gene Expression, and DNA mutations), students learned how DNA genes are expressed within the cell through the processes of transcription and translation. They also learned how DNA mutations can directly lead to diseases such as cancer, Sickle Cell Anemia, Cystic Fibrosis, and Tay-Sachs disease by producing faulty proteins. But how does DNA—found inside each of our cells—manifest itself as observable traits? How does our DNA control the color of our eyes, how tall we are, or if we are right or left handed? And if DNA is passed down from parent to child, how can two parents with brown hair and brown eyes have a child with red hair and blue eyes? Is it possible for or two parents with normal vision to have a child who is color-blind? Do you know how to predict the outcome of such genetic crosses?
