line up in the middle of the cell.
1. _____What is the name of this phase of mitosis?
A. metaphase
B. telophase
C. anaphase
D. prophase
2. ______During the cell cycle,
A. DNA is replicated directly after the completion of mitosis.
B. DNA is replicated once before mitosis and again before cytokinesis.
C. DNA is replicated during mitosis.
D. DNA is replicated before mitosis begins.
3. _____The cell cycle involves the growth, replication, and division of a
eukaryotic cell.
Mitosis most directly plays a role in
A. the growth of a cell after cell division.
B. the transport of nutrients within a cell.
C. the division of a cell's nucleus.
D. the metabolic processes of a cell.
4. _____During the interphase stage of the cell cycle,
A. the cell divides into two unique daughter cells.
B. the cell's chromosomes are duplicated.
C. the cell's chromosomes condense into rod-like structures.
D. the cell divides into two identical daughter cells.
5. ______Cytokinesis is a process that occurs during the cell cycle. During
cytokinesis,
A. the cytoplasm is divided to form two separate cells.
B. the chromosomes of the cell are duplicated.
C. the cell grows and performs normal life processes.

transcription?
A. DNA transcription only occurs in multicellular organisms, while DNA replication
occurs in all organisms.
