to cause cancer, proto-oncogenes require 1 (or) 2 allele(s) to be mutated and are therefore considered dominant (or) recessive. this results in of function.

To cause cancer, proto-oncogenes require both alleles to be mutated and therefore are considered dominant. The mutation results in a gain of function.

Several protein-controlled feedback systems regulate the cell cycle. Kinases and cyclins are two classes of proteins that regulate the cell cycle. By attaching to kinases, cyclins selectively activate cyclin-dependent kinases (CDK). A phosphate group from ATP is transferred from one molecule in a cell to another by kinases, which are enzymes. They act as a control switch in many cellular processes, controlling other cellular processes and turning a function on or off. They frequently play a part in starting a chain of events. At crucial points in the cell cycle, a group of proteins known as cyclins are created quickly. Following cyclin activation, CDK enzymes phosphorylate additional target molecules to either activate or inactivate them.
