Synthetic rescue is like a superhero team-up where one hero helps another hero who has a weakness they can't overcome on their own. In science, it's when one gene, which causes a problem in a cell or organism, is fixed by adding another gene that can help the first gene work properly.
Think of it like a puzzle where you have two pieces that don't fit together. But, if you add a third piece, it can make them fit together perfectly.
Scientists can use synthetic rescue to study genetic diseases, find new treatments, and learn more about how cells and organisms work. It's like having a secret weapon to help fix problems that would otherwise be too big to solve.
