What occurs during prophase?

Back

During prophase, chromosomes become visible, the nuclear envelope disappears, and spindle fibers begin to form.

What happens in metaphase?

Back

In metaphase, chromosomes align in the middle of the cell, attached to spindle fibers.

What is anaphase?

Back

Anaphase is the phase where sister chromatids are pulled apart to opposite ends of the cell.

What occurs during telophase?

Back

During telophase, chromosomes uncoil into chromatin, the nuclear envelope reappears, and spindle fibers disappear.

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate cells.

What is the purpose of mitosis?

Back

The purpose of mitosis is to ensure that each new cell receives an identical set of chromosomes.

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including G1, S, and G2 phases.

What happens during the G1 phase?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.
