Scientists have reported that more than 95% of the factors that lead to some types of cancers are caused by random DNA-copying errors. During which phase of the cell cycle do these DNA-copying errors most likely occur?

M phase

G₁ phase

G₂ phase

S phase

When cells lose their ability to regulate the cell cycle, they can divide at an accelerated rate and form a mass of cells. This mass of cells is referred to as --

an embryo

a gland

an organ

a tumor

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?

Antibody activity is unregulated

Somatic cell growth is inhibited

ATP production is inhibited

Cell division is unregulated

Throughout the cell cycle, the cell performs checkpoints to ensure that each phase is proceeding as normal. However, sometimes checkpoints are missed or fail.
During what stage of the cell cycle do mutations occur AND what is the result of mutations if the checkpoint is skipped or fails?

Increased the production of functional gametes

Decreased genetic variability of offspring

Decreased number of altered genes

Increased chance of cancer

Apoptosis is a programmed form of cell death that helps maintain healthy tissues. If a cell is damaged beyond repair but fails to go through apoptosis, what is the most likely consequence?

The cell will be replaced by new cells produced during normal tissue repair.

The cell will repair its DNA and then return to the cycle without problems.

The cell will pause in G₀ phase and remain inactive for the rest of its life cycle.

The cell will continue dividing with mutations, which may result in cancer.

Apoptosis is the process of programmed cell death that removes old or damaged cells. However, too much apoptosis can be harmful.
What is one negative effect of too much apoptosis?

Too much apoptosis will cause cells to divide too quickly and form tumors.

Too much apoptosis stops the body from making any new cells.

Too much apoptosis will destroy healthy cells faster than they can be replaced.

Too much apoptosis allows damaged cells to remain in the body and continue dividing.
