Detailed explanation-1: -So, the correct answer is ‘They show contact inhibition’.
Detailed explanation-2: -Proapoptotic Regulation in Tumor Cells Cancer cells are ‘primed for death’ meaning that they are closer to triggering the apoptotic pathway than normal cells [17]. The sensitivity for apoptotic signals increases in these primed cells [3].
Detailed explanation-3: -Which of the following is not a characteristic of apoptotic animal cell? Explanation: In apoptotic cells the mitochondria are either shrunken or remains of the same size. The ER on the other hand may be swollen. Remaining options are correct events happening during apoptosis.
Detailed explanation-4: -Cancer cells grow and divide at an abnormally rapid rate, are poorly differentiated, and have abnormal membranes, cytoskeletal proteins, and morphology. The abnormality in cells can be progressive with a slow transition from normal cells to benign tumors to malignant tumors.
