Transposons, often called “jumping genes,” are DNA sequences that can move from one location to another within a genome. They were first discovered by Barbara McClintock in the 1940s. Unlike most DNA, which stays in one place, transposons can change positions, sometimes disrupting genes or altering the genome’s function.

This movement can lead to mutations, which can be harmful, beneficial, or neutral. Transposons play a role in evolution by creating genetic diversity, but they can also cause diseases if they insert themselves into critical areas of the DNA. Overall, transposons are a fascinating part of how genomes evolve and adapt.
