Definition of Prophase chromosome

Prophase chromosome: A chromosome at the prophase stage in the cell cycle, before metaphase (when a chromosome is most highly condensed). The chromosomes in prophase are distended and often tangled like a ball of twine within the nucleus of the cell. However, when fine chromosomal details are important, prophase chromosomes are frequently selected for high resolution chromosome banding and analysis.
