Most of us know that traits like eye color, height, and even some of our behaviors are related to our genes. But do you know what makes up a gene, or how genes work? Have you ever wondered about DNA, RNA, or mRNA? It can seem confusing, but MedlinePlus can help you make sense of it all.
Detailed information about genes and genetic conditions has been added to MedlinePlus, an online health and wellness resource from the National Library of Medicine (NLM).
