Front

What is the G1 phase in the cell cycle?

Back

The G1 phase is the first stage of the cell cycle where the cell grows and prepares for DNA synthesis.

Front

What occurs during prophase in meiosis that differs from mitosis?

Back

During prophase in meiosis, homologous pairs of chromosomes become zipped together and crossing over occurs.

Front

Why can't a cell grow indefinitely?

Back

Cells cannot grow indefinitely because they are not programmed to do so.

Front

What is the S phase of the cell cycle?

Back

The S phase is the part of the cell cycle where a copy of DNA is synthesized within the nucleus.

Front

What happens during telophase?

Back

During telophase, the nucleoli reappear, a new nuclear envelope forms, and chromosomes unfold back into chromatin.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells.

Front

What is the role of checkpoints in the cell cycle?

Back

Checkpoints are regulatory points in the cell cycle that ensure the cell is ready to proceed to the next phase, preventing errors.

Front

What is cancer in relation to the cell cycle?

Back

Cancer is a disease characterized by uncontrolled cell division, often due to mutations in genes that regulate the cell cycle.

Front

What is cytokinesis?

Back

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