WebTogether, Raf, MEK, and the ERKs make up a three-tiered kinase signaling pathway called a mitogen-activated protein kinase (MAPK) cascade.(A mitogen is a signal that causes cells to undergo mitosis, or divide.)Because they play a central role in promoting cell division, the genes encoding the growth factor receptor, Raf, and c-Myc are all proto-oncogenes, … WebMar 4, 2024 · 243.3k + views. Hint: Rod and cone cells are types of photoreceptor cells found in the inner layer of the retina. These cells contain light-sensitive proteins known as photopigments. Thus these pigments are responsible for the detection of color and its intensity. The inner layer is the retina and it contains three layers of neural cells ...
