Scientists in Britain have finally solved one of the greatest mysteries of life: how chromosomes get their X shape. Chromosomes, discovered in the late 1800s, are DNA molecules which contain the genetic material of an organism.

But it was always a mystery how they are X-shaped. While Biology students across the world study that chromosomes get their shape during cell division, the exact reason behind their X shape was not known.
