Cell Cycle & Cancer PDOL review

What happens during interphase?

• the cell divides its cytoplasm

• the cell lyses and dies

• the cell grows normally

• the cells replicates its nucleus

Cell differentiation occurs when --

• specific DNA is mutated

• specific DNA is replicated

• Specific DNA remains the same

• Specific DNA is activated

Interphase is important to the growth of organisms because -

• replicates DNA

• replicates the cytoplasm

• separates chromosomes

• separates the cytoplasm

The cell cycle is important for which 2 reasons?

• Growth & metabolism

• Growth & repair

• Repair & replace

• Repair & mutate

Which phase of the cell cycle does DNA replication occur?

• G1

• S

• G2

• Mitosis

The reason stem cells become specialized is the -

• size of the cell enhances

• length of the cell cycle increases

• number of chromosomes increases

• specific genes are expressed

A mass of cells that loses its ability to divide correctly is called

• a mutation

• a tumor

• an embryo

• an organ

Muscle cells, live cells, and nerve cells are all different because -

• each cell replicates differently

• each cell expresses different genes

• each cell contains only part of the DNA

• each cell has different enzymes

Cancer is

• unregulated DNA replication

• unregulated cell lyses

• unregulated enzymes in cells

• unregulated cell division

Cytokinesis is

• when the nucleus divides

• when the cytoplasm divides

• when the chromosomes divide

• when the mitochondria divides
