The study found that Kid, a protein that helps move chromosomes during cell division, actually works in pairs and can move continuously along tiny tubes in cells. This protein can also help move DNA, and its ability to pair up makes it work better. These findings show that Kid should be seen as a more powerful motor than we thought before.
