Cell Cycle

All of these are stages of mitosis, except

• prophase
• metaphase
• telophase
• interphase

During the cell cycle, which phase does the cell spend most of its time?

• cytokinesis
• interphase
• prophase
• metaphase

A membrane that encloses the cells nucleus and separates the chromosomes from the rest of the cell is

• cell membrane
• cell wall
• nuclear membrane
• spindle fibers

The sequence of stages of growth and division that a cell undergoes is called 

• cell 
• cytoplasm
• cell cycle
• mitosis

Cylinder shaped organelles found in animal cells that help form spindle fibers are

• centriole

• centromere

• chomatid

• chromosome

The basic building block of all living organisms is

• tissue
• cell
• organ 
• organ system

The point on the chromosome where the two chromatids are held together is the

• centromere
• centriole
• chromosome
• chromatid

The structure of coiled DNA and proteins that forms in a cell's nucleus prior to mitosis is 

• centromere
• centriole
• chromosome
• chromatid

Two identical copies of a chromosome is

• centromere
• centrosome
• chromatid
• chromosome

Contains the genetic material and serves as the control center of the cell

• nuclear membrane
• spindle fibers
• nucleus
• telophase
