anaphase etymology

Etymology:

  • From Ancient Greek:
    • "ana-" (ανά): prefix meaning "up," "away"
    • "-phase" (φάσις): "phase," "stage"

Meaning:

Anaphase is the stage of mitosis or meiosis in which the chromosomes, which have been duplicated and aligned at the metaphase plate, are separated and moved to opposite poles of the spindle.

Origin:

The term "anaphase" was first used in the early 20th century by American cytologist Edmund Beecher Wilson. It was coined to describe the phase of cell division in which the chromosomes move "upward" (i.e., towards the poles of the spindle) after being attached to spindle fibers during metaphase.
