A series of questions and answers related to cell biology, covering topics such as the cell cycle, mitosis, and the immune system. It is designed to help students prepare for a certification exam in this field. Questions on the phases of the cell cycle, the stages of mitosis, and the different types of cells involved in the immune response. It also covers key concepts such as dna replication, cell cycle control, and the role of tumor suppressor genes.

name the 4 phases of the cell cycle Correct Answer: G1 Phase S Phase G2 Phase M Phase name the 4 stages of mitosis Correct Answer: Prophase Metaphase Anaphase Telophase Which is the longest phase of the cell cycle, lasting about 10 hours Correct Answer: S Phase What is the shortest phase of the cell cycle
Correct Answer: M Phase (Mitosis) these cells have receptors that determine if cells of cells they encounter are self or non- self. Their role is to destroy non-self cells Correct Answer: Natural Killer Cells Mitosis phase in which Nuclear envelope has disappeared, and chromosomes move toward the cell equator. Sister chromatids have not separated. The metaphase checkpoint ensures that the chromosomes are aligned properly before separation. Correct Answer: Metaphase Mitosis phase in which Centrioles move toward opposite poles, and the nuclear envelope breaks down. Correct Answer: Prophase Mitosis phase in which Two sister chromatids separate into chromosomes. Correct Answer: Ananphase Mitosis phase in which Nuclear envelope has disappeared, and chromosomes move toward the cell equator. Sister chromatids have not separated. A checkpoint ensures that the chromosomes are aligned properly before separation. Correct Answer: Metaphase
Correct Answer: G2 phase During which phase of the cell cycle do cells enlarge and pass a checkpoint that determines the cell is ready to divide Correct Answer: G2 phase three types of granulocytes Correct Answer: neutrophils, eosinophils, basophils _________, including Natural killer cells, granulocytes and macrophages are the second line of defense in the immune system (after skin, mucus membranes and gut flora) Correct Answer: Phagocytes nonspecific immunity Correct Answer: phagocytosis and inflammation (2nd line of defense) Learned specific immunity Correct Answer: 3rd line of defense which includes antibodies and lymphocytes 2 types of lymphocytes Correct Answer: T cells and B cells
important tumor suppressor gene, sometimes called the "suicide gene." Correct Answer: p53 gene
