Unit 2 Test

Front

What is cancer?

Back

Cancer is a disorder where human body cells lose the ability to control cell growth, which can lead to the formation of tumors.

Front

What phase of the cell cycle is responsible for DNA replication?

Back

The S phase (Synthesis phase) of the cell cycle is where DNA replication occurs.

Front

List the stages of mitosis in the correct order.

Back

The correct order of the stages of mitosis is Prophase, Metaphase, Anaphase, and Telophase.

Front

What is the stage of mitosis where chromosomes align in the center of the cell?

Back

The stage of mitosis where chromosomes align in the center of the cell is called Metaphase.

Front

What is the complementary DNA strand for the sequence ATA CGC TAA ATC?

Back

The complementary DNA strand for the sequence ATA CGC TAA ATC is TAT GCG ATT TAG.

Front

Define interphase in the context of the cell cycle.

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication and cell growth.

Front

What is the role of mitosis in cell division?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, ensuring equal distribution of genetic material.

Front

What happens during prophase of mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What is anaphase in mitosis?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

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

Back

The S phase is significant because it is when DNA is replicated, ensuring that each daughter cell receives an identical set of chromosomes.
