Media Image

Scientists determined the total mass of DNA from a sample of animal cells. The masses of equal numbers of cells were taken during three different stages of the cell cycle. Stage I contains cells massed during G1 of the cell cycle.

Which statement best describes the cells during Stage II?

The cells have replicated their DNA, but have not completed mitosis and cytokinesis.

The cells have completed mitosis and cytokinesis without replicating their DNA.

The cells have replicated their DNA and completed mitosis and cytokinesis.

The cells have temporarily exited the cell cycle without replicating their DNA.

Answer explanation

During Stage II, the cells have replicated their DNA, but have not completed mitosis and cytokinesis. Therefore, the mass of DNA is double the mass of the DNA in stages I and III.

Normal cells that have a contact inhibition feedback mechanism that prevents the cells from replicating when other cells are touched. A diagram of cells with contact inhibition and cells without contact inhibition is shown. Which statement best describes what will happen to cells in an organism that lack contact inhibition?

The cells will continue to grow, causing a tumor in the body.

The cells will replicate normally, replacing body cells that die.

The cells will replicate until the food supply for each cell is used, causing each cell to die.

The cells will stop replicating once one layer is produced, as other body cells will crowd them out.

Answer explanation

Contact inhibition is a mechanism that stops the cell cycle and prevents cells from performing replication/proliferation and growth. The cells in an organism that lack contact inhibition will continue to replicate/proliferate and grow, and potentially lead to the development of tumors.
