The shape is primarily due to a protein known as shugoshin, which means 'guardian spirit' in Japanese.
DNA is the biological code of all life on Earth. All living organisms contain genetic information in the form of a DNA code. As demonstrated by school textbooks, DNA is in the formation of an X. However, what causesNow, scientists from the Netherlands Cancer Institute have found a potential answer.
During cell division, the cohesin rings that hold the cells together open up, releasing the two arms of the DNA. Because of a protein called shugoshin , these rings are attached in the middle of the DNA. The official statement explains this complex biological process that works to create this shape: “Shugoshin uses a molecular key that fits precisely into a kind of keyhole in cohesin. In doing so, it locks the cohesin rings. Because shugoshin works in the center of chromosomes, it is only there that it locks the rings. That gives chromosomes their X shape.
