Snippet Of RNA Helps Make Individuals Remarkably Alike

Uniformity, or singleness of form, is a general property of life. Biologists have long pondered how this feature is produced in the face of such great variation in genetics and environmental conditions. Researchers now have identified a microRNA that is critical to the robustness of the molecular network that helps regulate uniformity. This knowledge could lead to a better understanding of cancer cells, which do not act in controllable, uniform ways.
