What is a tumor?

A stage in the cell cycle?
A mass of cells?
A checkpoint in the cell cycle?
A cell that results from mitosis?

A tumor is a mass of abnormal cells that have formed together. It can be either benign or malignant (cancerous).

A stage in the cell cycle refers to one of the distinct phases that a cell goes through during its life cycle, including interphase (G1, S, and G2) and mitosis or meiosis.

A mass of cells can refer to a collection of cells that have come together, which can include tumors, as well as other types of cellular aggregates.

A checkpoint in the cell cycle is a control point at various stages of the cell cycle where regulatory proteins assess the fidelity and completion of critical processes before allowing the cell to proceed to the next stage. These checkpoints help to ensure the proper progression and integrity of the cell cycle.

A cell that results from mitosis is called a daughter cell. During mitosis, a parent cell divides into two identical daughter cells that contain the same genetic information as the parent cell.

A tumor is an abnormal growth of cells in the body. It is often referred to as a mass or a lump. Tumors can be either benign or malignant. Benign tumors are non-cancerous and do not spread to other parts of the body. Malignant tumors, on the other hand, are cancerous and have the potential to invade nearby tissues and spread to other parts of the body.

In the cell cycle, different stages occur as cells go through the process of dividing and replicating. One of the key stages in the cell cycle is called mitosis. Mitosis is the process in which a single cell divides into two identical daughter cells. It is important for growth, repair, and maintenance of tissues in the body.

A mass of cells refers to a collection or accumulation of cells in a specific location. This can occur in various situations, such as during wound healing or in the formation of tumors.

Checkpoints in the cell cycle are critical control points that ensure the proper progression of the cell cycle and prevent the division of damaged or abnormal cells. These checkpoints act as quality control mechanisms and monitor factors such as DNA damage, cell size, and DNA replication before allowing the cell to proceed to the next stage of the cell cycle.

A cell that results from mitosis is called a daughter cell. During mitosis, a parent cell divides into two identical daughter cells. These daughter cells contain the same genetic material as the parent cell and are capable of further growth and division.
