<span>A change in a DNA sequence is called a mutation. Mutation occurs through a large variety of processes. The most written about in the press is of course the chemical-induced mutations. There is a large variety of chemicals that can induce mutations, most of time by binding to the DNA itself and breaking it, forcing an imperfect reparation or by blocking the replication of the DNA, which will force the replication system to duplicate it imperfectly, i really hope this helps, good luck babe!!</span>
Answer:
This would be an example of nonpoint source pollution.
Explanation:
The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^
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.
