Video transcript

Hello everyone here We have a question that says which of the following statement incorrectly describes the brain cells? They they have the same genome as the red blood cells. That is correct. B They function differently from the liver cells. That is obviously correct. See they are expressed differently from kidney cells. That is correct. The skin cells, liver cells and brain cells are made up of the same proteins. That is incorrect. If they were made up of the same proteins they would all be the same but they have the same D. N. A. But they are different because of their differing proteins. So our answer here is the skin cells, liver cells and brain cells are made up of the same proteins. Is incorrect. Thank you for watching. Bye.
