Summary Introduction
To determine:
The effect on the shape of rubber band if it is twisted many times and its similarity and differences with the cell division.
Introduction:
Binary fission is the process by which a cell divides mitotically or meiotically. The first step of cell division is the duplication of the entire genome. The genome consists of one or more chromosome. Chromosomes are known as the individual molecules of DNA with their associated proteins
