In prophase,

A) the chromosomes condense, shorten, and thicken.
B) the spindle fibers disappear.
C) the chromosomes replicate.
D) cytokinesis occurs.
E) DNA is synthesized.

Chromosomes Condense

The process by which chromosomes become shorter and thicker, making them visible under a microscope, typically occurring during cell division.

Spindle Fibers

Filaments formed during cell division that help segregate chromosomes into the daughter cells.

Cytokinesis

The process during cell division in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.
