Cell Cycle

Front

What is chromatin?

Back

Chromatin is a complex of DNA and proteins found in the nucleus of eukaryotic cells, which condenses to form chromosomes during cell division.

Front

What phase of the cell cycle is characterized by the alignment of chromosomes at the cell's equatorial plane?

Back

Metaphase is the phase of the cell cycle where chromosomes align at the cell's equatorial plane.

Front

What occurs during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis. Chromatin is not condensed into chromosomes during this phase.

Front

If a unicorn's hair cell has 78 chromosomes, how many chromosomes will each daughter cell have after mitosis?

Back

Each daughter cell will have 78 chromosomes after mitosis, as the chromosome number is maintained.

Front

List the stages of the cell cycle in the correct order.

Back

The stages of the cell cycle in the correct order are interphase, mitosis, and cytokinesis.

Front

What is the role of mitosis in the cell cycle?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, allowing for growth and repair.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of the cell cycle where the cytoplasm divides, resulting in two separate daughter cells.

Front

What happens to chromatin during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What is the significance of the G1 phase in interphase?

Back

The G1 phase is significant for cell growth, organelle duplication, and preparation for DNA synthesis.

Front

What is the S phase in the cell cycle?

Back

The S phase is the part of interphase where DNA replication occurs, resulting in two sister chromatids for each chromosome.
