Unit 4 Cell Cycle, DNA Replication, Cancer

Front

What is the primary reason benign tumors are not considered a threat?

Back

They do not spread.

Front

What structures are responsible for moving chromosomes during mitosis?

Back

Spindle fibers.

Front

In which phase of the cell cycle does the cell spend most of its life?

Back

Interphase.

Front

What does interphase include?

Back

All are correct.

Front

What is the term for one half of the X shape of a chromosome?

Back

Sister chromatid.

Front

What are the three main stages of interphase?

Back

G1 phase, S phase, G2 phase.

Front

What occurs during the S phase of interphase?

Back

DNA replication.

Front

What is the role of spindle fibers during cell division?

Back

To separate sister chromatids and pull them to opposite poles of the cell.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors do not invade surrounding tissues or spread, while malignant tumors do.

Front

What is the significance of the G1 phase in the cell cycle?

Back

It is the first growth phase where the cell grows and prepares for DNA replication.
