Cells & the Cell Cycle Review

Front

What is a characteristic of cancer cells?

Back

Uncontrolled cell division.

Front

What is the main purpose of the G2 phase in the cell cycle?

Back

Cell growth and preparation for mitosis.

Front

What are chromatids?

Back

Chromatids are the two identical halves of a duplicated chromosome, which are joined together by a centromere.

Front

What is the purpose of the cell cycle?

Back

The cell cycle allows multicellular organisms to grow and divide.

Front

What phase of mitosis is characterized by the alignment of chromosomes at the cell's equator?

Back

Metaphase.

Front

What occurs during the S phase of the cell cycle?

Back

DNA replication.

Front

What is cytokinesis?

Back

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

Front

What is the role of centrioles in cell division?

Back

Centrioles help in the formation of the spindle fibers that separate chromosomes during mitosis.

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 difference between mitosis and meiosis?

Back

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