Cell Division in Normal Cells Is Precisely Controlled as Follows

question 1

Multiple Choice

Cell division in normal cells is precisely controlled as follows:

• A) Angiogenesis balances cell division and programmed cell death so cells don't over-accumulate.
• B) The gene NF-1 stops cell division if it is happening too quickly and cells are piling up, potentially resulting in a tumor.
• C) Proto-oncogenes urge a cell to divide and tumor suppressor genes stop cell division. The two keep growth from getting out of control.
• D) Proto-oncogenes urge a cell to divide, and oncogenes stop division. The two keep growth from getting out of control.
• E) A chromosome called the Philadelphia chromosome controls cell division.
