Front

What phase of mitosis involves the disintegration of the nuclear membrane?

Back

Prophase

Front

What is replicated during the S phase before cell division?

Back

Front

What is the main purpose of mitosis?

Back

To divide a cell's nucleus and its contents into two identical nuclei.

Front

What happens during the G1 phase of the cell cycle?

Back

The cell grows and synthesizes proteins necessary for DNA replication.

Front

What is the role of DNA polymerase during DNA replication?

Back

To synthesize new DNA strands by adding nucleotides complementary to the template strand.

Front

What occurs during metaphase in mitosis?

Back

Chromosomes align at the cell's equatorial plane.

Front

What is the significance of the S phase in the cell cycle?

Back

It is the phase where DNA is replicated, ensuring each daughter cell receives a complete set of chromosomes.

Front

What is cytokinesis?

Back

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