Mitosis test review

What is the name of the process in the diagram.

• metaphase

• mitosis

• meiosis

• mycosis

Refer to the diagram. Arrange the stages of mitosis in order.

• I, II, III, IV, V, VI

• VI, II, I, IV, V, III

• III, VI, I IV, II, V

• V, III, IV, I, II, VI

Refer to the diagram. What is occurring within the cell labeled II?

• a cleavage furrow is forming to divide the cell into two daughter cells

• DNA is replicated so there are two copies of each chromosome in each daughter cell

• chromatin is condensing to form visible chromosomes

• the spindle is attaching to chromatids to move them to the middle

Which stage of the cell cycle in the diagram above shows the formation of spindle fibers and chromatin condensing into chromosomes?

• I

• III

• IV

• VI

What is the purpose of mitosis

• each daughter cell has half the amount of DNA of parent cells

• new nuclei have an exact copy of DNA

• reproduction of mitochondria and chloroplasts

• prevents the occurrence of cancer cells

In order for a cell to successfully divide, the cell must first:

• duplicate its genetic information

• decrease it's volume

• increase in size

• decrease it's number of organelles

Sister chromatids are attached to each other at an area called

• centriole

• centromere

• spindle

• chromosome

If a cell has 22 chromosomes, how many chromosomes will each of it's daughter cells have after cytokinesis during mitosis?

• 8

• 11

• 22

• 24

Where does DNA replication occur?

• G1

• S

• G2

• M

What occurs at G1?

• chromatin condenses to form chromosomes

• cleavage of cytoplasm and formation of cell plate

• period of growth and development between mitotic divisions

• nuclear membrane, nucleolus and chromatin fade
