Summary:
- This article discusses a new technology that allows scientists to make mouse genes visible and trackable under a microscope.
- This technique, called "RAINBOW," involves inserting fluorescent tags into mouse DNA to label specific genes, allowing researchers to observe how those genes are expressed and regulated over time.
- The ability to visualize gene activity in living mice can provide valuable insights into the genetic mechanisms underlying various biological processes and diseases, potentially leading to new treatments and therapies.
