Quick 10Q: Mitosis

Front

What is the phase of mitosis where sister chromatids are separated to opposite poles of the cell?

Back

Anaphase

Front

What occurs before the process of mitosis?

Back

DNA is replicated.

Front

What is the phase of mitosis where sister chromatids align on the metaphase plate in the middle of the cell?

Back

Metaphase

Front

Which checkpoint ensures that all microtubules are attached to kinetochores?

Back

M checkpoint.

Front

What is the phase of mitosis involving the pairing of sister chromatids and condensation of chromatin into chromosomes?

Back

Prophase.

Front

What is the main purpose of mitosis?

Back

To divide a single cell into two identical daughter cells.

Front

What are sister chromatids?

Back

Identical copies of a chromosome, connected by a centromere.

Front

What happens during prophase?

Back

Chromatin condenses into chromosomes, and the nuclear envelope begins to break down.

Front

What is the role of microtubules during mitosis?

Back

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

Front

What is the significance of the G1 checkpoint?

Back

It checks for cell size, nutrients, and DNA damage before the cell enters S phase.
