DNA and the Cell Cycle

Front

What happens to the number of chromosomes after mitosis?

Back

The number of chromosomes in the newly created cells will be the same as the original cell.

Front

What are identical halves of a chromosome called?

Back

Chromatids.

Front

During which phase of the cell cycle can chromosomes be identified?

Back

M phase.

Front

What is the result of the cell cycle?

Back

2 identical cells.

Front

In which phase do sister chromatids separate from each other?

Back

Anaphase.

Front

What is the role of the centromere in a chromosome?

Back

The centromere is the region where two sister chromatids are joined together.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in two copies of each chromosome.

Front

What is the function of the mitotic spindle?

Back

The mitotic spindle helps separate the sister chromatids during cell division.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical cells, while meiosis results in four genetically diverse gametes.

Front

What is cytokinesis?

Back

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