Verified
An epidermal growth factor (EGF) stimulates a cell to enter mitosis by binding to a receptor on the cell's plasma membrane. The EGF receptor is a product of a ____ gene.
A) repressor
B) structural
C) master
D) proto-onco
E) growth
Proto-Onco Gene
A normal gene which, when altered by mutation, becomes an oncogene that can contribute to cancer.
Epidermal Growth Factor
A protein that stimulates cell growth, proliferation, and differentiation by binding to its receptor, EGFR, on the cell surface.
Plasma Membrane
The double layer of lipids surrounding the cell's cytoplasm, controlling the entry and exit of materials to and from the cell.

Final Answer :
D
Explanation :
The EGF receptor is a type of receptor tyrosine kinase (RTK) and is encoded by a proto-oncogene. Proto-oncogenes are normal cellular genes that can become oncogenes if mutated or overexpressed, leading to excessive cell growth and division.
