Stages of Cell Division

Front

What happens during prophase?

Back

Chromatin condenses into visible chromosomes, nuclear membrane and nucleolus break down, spindle fibers form from centrosomes and move toward opposite poles of the cell.

Front

What is the role of spindle fibers in prophase?

Back

Spindle fibers help separate the chromatids during cell division.

Front

What occurs during metaphase?

Back

Chromosomes line up along the equatorial plate, and spindle fibers attach to the centromeres of each chromosome.

Front

What happens during anaphase?

Back

Centromeres split, spindle fibers shorten, and sister chromatids are pulled apart to opposite ends of the cell.

Front

What marks the end of nuclear division in telophase?

Back

Chromatids reach the poles, new nuclear membranes form, chromosomes uncoil back into chromatin, and the nucleolus reappears.
