Quick 10Q: Mitosis

Front

What is the G1 checkpoint in the cell cycle?

Back

The G1 checkpoint is a control mechanism that determines whether a cell should proceed to divide, ensuring that conditions are favorable for cell division.

Front

What occurs during the S phase of the cell cycle?

Back

During the S phase, DNA is replicated, resulting in the formation of sister chromatids.

Front

What is the purpose of the G2 checkpoint?

Back

The G2 checkpoint ensures that all DNA has been replicated correctly and checks for any errors before the cell enters mitosis.

Front

What happens during telophase in mitosis?

Back

During telophase, the nuclear envelope forms around each set of separated chromosomes, marking the near end of mitosis.

Front

What is the role of microtubules during anaphase?

Back

Microtubules pull sister chromatids apart to opposite poles of the cell during anaphase.

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What is chromatin?

Back

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

Front

What is the significance of the M phase in the cell cycle?

Back

The M phase is the stage of the cell cycle where mitosis and cytokinesis occur, leading to the division of the cell into two daughter cells.

Front

What occurs during prophase?

Back

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

Front

What is cytokinesis?

Back

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