Oncogenes are mutated forms of genes. Oncogenes can transform a cell into a tumor cell. Some tumor cells are benign, while others are malignant. How does the presence of an oncogene lead to the formation of a tumor?

• ATP Production is inhibited.

• Cell division is unregulated.

• Somatic cell growth is inhibited.

• Antibody Activity is unregulated.

The diagram shows cells in different phases of mitosis. A student is trying to find a cell in a particular phase of mitosis. The student is looking for evidence that spindle fibers are separating the chromosomes to ensure that each new nucleus has one copy of each chromosome. (View Image)

Which cell is in the phase of mitosis that the student is searching for?

• Cell 1

• Cell 2

• Cell 3

• Cell 4
