Which processes are involved in the development of cancer?I. Mutations occur in oncogenes.II. Oncogenes prevent cancer.III. Oncogenes affect cell cycle regulatory proteins.A. I and II onlyB. I and III onlyC. II and III onlyD. I, II and III

When dramatic changes occur during the cell cycle, cancer may develop. Which mutation that affects the cell cycle would likely lead to the development of cancer? [B.2G]Select one:a.A mutation that suppresses the rate of mitosisb.A mutation that inhibits meiosisc.A mutation that stimulates the rate of cell divisiond.A mutation that increases the expression of tumor suppressor genes

Tumor suppressor genes put the “brakes” on the cell cycle. However, the inactivation or under-expression of tumor suppressor genes allow the cell cycle to progress indefinitely, thus promoting cancer. By which of the following mechanisms could a tumor suppressor gene be altered in a way that contributes to the development of cancer?1. Gene amplification 2. Single base pair changes 3. DNA cytosine methylation 4. Histone acetylation Group of answer choices1, 2, 41, 2, 31 and 32 and 33 and 4

A patient’s cancer cells are found to be resistant to apoptosis. Which cellular process is likely disrupted?A) Cell cycle progressionB) DNA replicationC) Programmed cell deathD) Protein synthesis

Which of the following statements about cancer cells is correct?1. Passenger mutations can occur without the onset of a tumor.2. Cancer cells are derived from a clone.3. Accumulation of driver mutations can lead to cancer.4. Intratumoral heterogeneity provides a good rationale for advancing precision medicine.A. 1, 2 and 3B. 1 and 3C. 2 and 4D. 4 onlyE. All of 1, 2, 3 and 4 are correc

. Tumour suppressor proteinsa) become hyperactive when excited by cell signalling factorsb) lose regulation when mutated, leading to oncogenesisc) normally function to stimulate cell growth and divisiond) prevent unneeded cell division
