Most mutations have no effect on organisms. Organisms all have large amounts of genetic code, most of which has no effect. As a result, mutation of this code is rarely meaningful.
The nucleus of the cell directs cell activity and acts like the control center. This is the place where gene activity is controlled in terms of the replication of the genes. In addition the movement and actions of the cell are also dictated from the nucleus.
