Review #7: The Cell Cycle (Mitosis)

Front

What is the total number of chromosomes in most human cells?

Back

46

Front

During which phase of the cell cycle do cells first begin to grow and copy their organelles?

Back

G1 phase

Front

What phase of mitosis involves the reformation of the nuclear membrane around daughter cells?

Back

Telophase

Front

What are the structures that appear as 'X' shapes during cell division?

Back

Chromosomes

Front

What happens if a cell undergoes mitosis without cytokinesis?

Back

One large cell with many nuclei.

Front

What is the purpose of mitosis in cell division?

Back

To ensure that each daughter cell receives an identical set of chromosomes.

Front

What are the four main stages of mitosis?

Back

Prophase, Metaphase, Anaphase, Telophase (PMAT).

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in the duplication of chromosomes.

Front

What is cytokinesis?

Back

The process that divides the cytoplasm of a parental cell into two daughter cells.

Front

What is the role of the spindle fibers during mitosis?

Back

To help separate the chromosomes and pull them to opposite poles of the cell.
