During mitosis, what process decreases the possibility that chromsomal mutations might occur due to tangling and breakage of DNA?

• aligning on the equator/middle

• appearance of a spindle

• dense coiling of DNA into chromosomes

• break down of nuclear membrane

What is the time between cell divisions in the life cycle of the cell called? (This is the time when the cell is not dividing.

• anaphase

• interphase

• prophase

• metaphase

At the end of mitosis, the cell membrane pinches in, dividing the cytoplasm into 2 cells. This is known as

• synthesis

• cytokinesis

• anaphase

• replication

Which of the following correctly describes the end result of mitosis and cytokinesis?

• Three identical cells are formed

• One cell contains enough DNA for two cells

• Two daughter cells are produced that are genetically identical to the parent cell

• Four identical daughter cells are produced from each parent cell.

The two structures that "a" is pointing to consist of.

• identical DNA

• genes from both the mother and father

• uncoiled DNA

• chromosomes that have already separated

It is important that the two new cells produced during mitosis receive an exact copy of the original cell's genetic code? Which answer below does NOT contribute to this outcome?

• alignment of chromosomes on the equator

• replication of the DNA in the original cell

• division of the cytoplasm at the end of mitosis

• attachment of spindle fibers to every chromosome

The S stage of interphase stands for synthesis. What is synthesized?

• DNA

• Daughter Cells

• Spindles

• Nuclear membranes
