Cell Cycle and Mitosis REVIEW

Front

What stage of the cell cycle is responsible for DNA replication?

Back

S phase

Front

What are chromatids?

Back

One chromosome is made up of two chromatids.

Front

What is cytokinesis?

Back

The process of dividing the cytoplasm of a cell into two daughter cells after nuclear division.

Front

How does the presence of an oncogene lead to the formation of a tumor?

Back

Cell division is unregulated.

Front

What occurs just before the cell enters the G2 stage of the cell cycle?

Back

DNA replicates.

Front

What is the G1 phase of the cell cycle?

Back

The first gap phase where the cell grows and prepares for DNA replication.

Front

What happens during the G2 phase?

Back

The cell continues to grow and prepares for mitosis.

Front

What is the M phase?

Back

The mitotic phase where the cell divides its copied DNA and cytoplasm to form two new cells.

Front

What is the role of centrioles during mitosis?

Back

Front

What is the difference between benign and malignant tumors?
