Answer:

Explanation:

Similar to a guard at the outside of a club, deciding who should be allowed in and who to keep out, the cell membrane is semi-permeable, regulating the movement of substances in and out of the cell with the help of protein channels.

The cell membrane is a double layer of lipids (fats) and proteins that surround a cell and separates the cytoplasm/ organelles from its surrounding environment.

What is the relationship between proto-oncogenes and oncogenes? hints what is the relationship between proto-oncogenes and oncog
Elan Coil [88]
Oncogenes result from turning on, or activating proto oncogenes. Proto oncogenes are genes that code for positive cell cycle regulators, so proto oncogenes code for proteins that turn on cell division. Proto oncogenes are normal genes, but when they are mutated, they become oncogenes.  Oncogenes are expressed too much, which makes them  turn on cell division too much, which is cancer.
