Cell cycle, mitosis, and cancer

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M).

Front

During which phase does DNA replication occur?

Back

DNA replication occurs during the S phase of Interphase.

Front

What is the purpose of the G1 phase in the cell cycle?

Back

The G1 phase is primarily for cell growth and preparation for DNA synthesis.

Front

What happens during the G2 phase of the cell cycle?

Back

During the G2 phase, the cell continues to grow and prepares for mitosis by producing proteins and organelles.

Front

What is Interphase and how long does a cell typically spend in it?

Back

Interphase is the phase of the cell cycle where the cell spends most of its life, typically about 90% of the cycle.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to the other half by a centromere.

Front

What occurs during Prophase of mitosis?

Back

During Prophase, the nucleolus and nuclear membrane disappear, chromatin condenses into chromosomes, and spindle fibers begin to form.

Front

What is the significance of Metaphase in mitosis?

Back

In Metaphase, chromosomes align at the cell's equatorial plane, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

What are spindle fibers and what role do they play in mitosis?

Back

Spindle fibers are structures that help separate chromosomes during mitosis by attaching to the centromeres and pulling them apart.

Front

What is the difference between mitosis and cytokinesis?

Back

Mitosis is the process of nuclear division, while cytokinesis is the division of the cytoplasm, resulting in two separate daughter cells.
