What is the function of a centromere in a chromosome?

Back

The centromere is the region of a chromosome where the two sister chromatids are joined together. It plays a crucial role during cell division, ensuring that each daughter cell receives an identical set of chromosomes.

List the correct order of events in the cell cycle.

Back

1. Cell grows 2. DNA replicates 3. Cell prepares for mitosis 4. Cell divides.

Front

What are the stages of mitosis in the correct order?

Back

1. Prophase 2. Metaphase 3. Anaphase 4. Telophase.

Front

What is a chromosome?

Back

A chromosome is a long, thread-like structure made of DNA and proteins that contains genetic information. Chromosomes are found in the nucleus of eukaryotic cells.

Front

Where is genetic material located in a cell?

Back

The genetic material of a cell is located in the nucleus.

Front

What happens during the G1 phase of the cell cycle?

Back

During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication.

Front

What is the role of the spindle fibers during mitosis?

Back

Spindle fibers are responsible for separating the sister chromatids and pulling them to opposite poles of the cell during mitosis.

Front

Define cytokinesis and its significance in the cell cycle.

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells. It is significant because it completes the cell division process.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis is a type of cell division that results in two identical daughter cells, while meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What occurs during prophase of mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle apparatus begins to form.
