have a brand new DNA structure
What are chromosomes?
They attach to the DNA and pull it to the sides
They contain mitochondria
They contain ribosomes
DNA packaged into threadlike structures
What must occur before a cell can proceed to mitosis from the gap 2 stage of the cell cycle?
the cell triples its DNA
undergo cytokinesis
go through a full cell cycle
pass a critical checkpoint
Spinal cord injuries are difficult to treat because damaged nerce cells do not regenerate. Which of the following most accurately explains why damaged nerve cells no longer regenerate?
Mature nerve cells are in a resting state; the no longer divide during mitosis
Nerve damage disrupts the cell cycle at the G1 phase
Nerve damage disrupts the cell cycle at the S phase

G1 Phase
The photo shows one yeast cell. This cell makes up the entire organism. Which two processes will happen as the cell grows?
The number of cells will increase.
The cell will take in nutrients.
The cell will split in half and become two new cells.
The cell will increase in overall size.
A cell has two copies of each chromosome
at the beginning of the G1 phase.
once the nucleus of the cell divides.
after its first period of growth.
at the end of the S phase.
Why might cancer drugs affect cells in the hair and nails in addition to the cells they are intending to target?
We have the least amount of these cells in our bodies.
These cells are the weakest.
Treatments target cells that divide most frequently.
We have no way of knowing.
