Cell Cycle practice

Front

What happens to chromosomes during telophase of mitosis?

Back

Chromosomes begin to decondense and the two new nuclei begin to form.

Front

During which phase of the cell cycle is DNA replicated?

Back

Synthesis (S phase)

Front

What is the outcome of mitosis in terms of cell number?

Back

Mitosis starts with one cell and ends with two cells.

Front

What is the process called when cells in an embryo begin to turn on and off particular genes to become specific cell types?

Back

Differentiation

Front

Why must cells of organisms go through cell division?

Back

For growth, repair of damaged cells, and replacement of dying cells.

Front

What is the first phase of the cell cycle?

Back

Gap 1 (G1) phase.

Front

What is the main purpose of the S phase in the cell cycle?

Back

To replicate DNA.

Front

What occurs during the G2 phase of the cell cycle?

Back

The cell prepares for mitosis by producing proteins and organelles.

Front

What is the role of checkpoints in the cell cycle?

Back

To ensure that the cell is ready to proceed to the next phase.

Front

What is cytokinesis?

Back

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