**Cell Cycle and Mitosis

Front

What phase of the cell cycle do cells spend the majority of their lives in?

Back

Interphase

Front

What structure holds the replicated sister chromatids together?

Back

Centromere

Front

During which phase of the cell cycle is DNA replicated?

Back

Synthesis (S phase)

Front

What does chromatin refer to in terms of DNA structure?

Back

DNA that is relaxed like a bowl of spaghetti.

Front

List the phases of mitosis in order.

Back

Prophase, Metaphase, Anaphase, Telophase

Front

What is the main purpose of the cell cycle?

Back

To ensure proper cell division and replication.

Front

What are the two main stages of the cell cycle?

Back

Interphase and Mitotic phase (M phase).

Front

What occurs during the G1 phase of interphase?

Back

Cell growth and preparation for DNA synthesis.

Front

What is the role of the spindle fibers during mitosis?

Back

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

Front

What happens during prophase of mitosis?

Back

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