Okay kiddo, imagine you have a really long piece of rope. This rope is made up of smaller strings that are all twisted together. Now, imagine that some parts of the rope are twisted in a different way than other parts.
When the rope gets tangled up in these different twists, it creates something scientists call a g-quadruplex. Think of it like a knot in the rope, but instead of just one twist, there are four twists that make a special shape.
This shape is important because it can happen in DNA and it can affect how genes are turned on or off. Scientists study g-quadruplexes to try to understand more about how our cells work and how we can use that knowledge to help people stay healthy.
