Which of the following correctly describes the differentiation of cells?
Certain genes are added to cells to produce proteins that enable specific functions.
Certain genes are activated to produce certain proteins that enable specific functions.
Differentiated cells produce all proteins but destroy the proteins they do not use.
Differentiated cells release unused proteins into the blood for other cells to use.
During the process of differentiation
all sections of DNA are activated to determine the structure of a body cell
ONLY ONE section of DNA are deactivated to determine the structure of a body cell
only specific sections of DNA sequence are activated to determine the structure and functions of a body cell

What is the purpose the the cell cycle checkpoints?
To repair damaged cells before they enter cell division.
To remove damaged cells from an organism.
The invasion of the bloodstream by a malignant cell that takes up residence in a new location is called.
Metastasis
