Front

What does mitosis divide?

Back

Mitosis divides the nucleus.

Front

What phase of mitosis involves sister chromatids aligning on the plate in the middle of the cell?

Back

Metaphase.

Front

Which phase of mitosis involves sister chromatids on the middle plate?

Back

Metaphase.

Front

In which phase of mitosis does the nuclear envelope form?

Back

Telophase.

Front

Which phase of mitosis involves single chromatids moving to the poles?

Back

Anaphase.

Front

What is the purpose of mitosis?

Back

The purpose of mitosis is to ensure equal distribution of chromosomes to daughter cells.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome, connected by a centromere.

Front

What happens during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the role of the spindle fibers during mitosis?

Back

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

Front

What occurs during anaphase?

Back

During anaphase, the sister chromatids are pulled apart and move toward opposite poles of the cell.
