The correct option is this: PROTO ONCOGENES BECOMES ONCOGENES.
Proto oncogenes genes are those genes that regulate the process of normal cell division in the living system. These cells starts cell division when necessary and terminate the cell division when the necessary cells have been formed. When these genes lose the power to regulate cell division, the cells continue to divide indefinitely without stopping and this leads to a medical condition called cancer. At this stage, the proto oncogenes have been turned into oncogenes, which are genes that caused uncontrolled cell cycle divisions.
The process is called Erosion. During the Erosion, materials from one place such as soil and rocks will be transport to another location. The process is also contrast to the process called deposition which responsible for the control of the arrival of the materials to a new place like the rocks from Blue ridge Mountain to Virginia's Coast.
