A look into the nuclei of fly embryos

Caption

A look into the nuclei of fly embryos. The enhancer (blue) and promoter (green) need to be in physical proximity for gene activity (red) to occur. Following the motion of these elements in real-time reveals that DNA is densely packed and therefore close together, yet exhibits fast motion, allowing the elements to come into contact quickly.
