B) changes in the order of cell cycle stages
C) lack of appropriate cell death
D) inability to form spindles
E) inability of chromosomes to meet at the metaphase plate

Question

Quizplus · Accepted Answer

A lack of appropriate cell death, also known as apoptosis, can lead to the accumulation of abnormal cells and the formation of a tumor. Normally, when cells become damaged or abnormal, they undergo apoptosis to prevent further damage or replication. However, cancer cells can evade apoptosis and continue to reproduce, leading to tumor growth.

Answer: A, B, D, and E are possible factors that could contribute to the development of cancer but are not as directly related to tumor formation as a lack of appropriate cell death. Enhanced anchorage dependence (A) can prevent cells from detaching from the extracellular matrix and spreading throughout the body, but it is not a requirement for tumor formation. Changes in the order of cell cycle stages (B) and inability to form spindles (D) can lead to abnormal cell division, but they do not necessarily result in tumor formation. Similarly, inability of chromosomes to meet at the metaphase plate (E) can disrupt cell division, but it does not directly cause tumor growth.
