- Title
A Cell Machine.
- Abstract
The article focuses on the scientific discovery by a group of scientists from the universities of Yale and Lehigh regarding the assembly of a cellular structure, which is responsible for cell division. Using time-lapse photography and computer modeling, the group was able to identify a tiny muscle-like ring used by cells to pinch them into two genetically identical daughter cells at the end of mitosis. Scientists also believe that the contractile ring are acting like a purse string that eventually draws together before severing one cell into two. A study suggests that a failure of the cell-separating machinery may be associated with tumor development in cancer.
