Unit 2 Cell Cycle

Front

What are carcinogens?

Back

Carcinogens are cancer-causing agents; chemicals that cause cancer by mutating DNA.

Front

What are sister chromatids?

Back

Sister chromatids are two identical chromatids that are joined together at the centromere.

Front

What is a benign tumor?

Back

A benign tumor consists of abnormal cells that typically remain clustered together; it may be harmless and easily removed.

Front

What happens during anaphase?

Back

During anaphase, sister chromatids separate, pulling away from each other and becoming individual chromosomes, moving to opposite ends of the cell.

Front

What occurs during metaphase?

Back

During metaphase, spindle fibers connect to the centromeres, and chromosomes line up in the middle of the cell.

Front

What is the cell cycle?

Back

The cell cycle is the series of events that take place in a cell leading to its division and duplication (replication).

Front

What are the main phases of the cell cycle?

Back

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (M).

Front

What is the role of spindle fibers?

Back

Spindle fibers are structures that help separate sister chromatids during cell division.

Front

What is a malignant tumor?

Back

A malignant tumor consists of cancerous cells that can invade nearby tissues and spread to other parts of the body.

Front

What is the significance of the centromere?

Back

The centromere is the region of a chromosome where sister chromatids are joined and where spindle fibers attach during cell division.
