anaphase

1 8.8

Stage of cell division when chromosomes move to opposite ends of the cell

noun
/ˈænəˌfeɪz/

Specialized

: anafase

Cohesin is a protein that binds sister chromatids together, and its degradation allows the sisters to be pulled apart in anaphase.

Examples

McEwen and colleagues (1997) determined that in PtK cells, the number of microtubules attached to each kinetochore increases from prometaphase to anaphase.

The SAC prevents the transition from metaphase to anaphase until proper alignment and tension are detected by a series of proteins.

Academic text (2009)
Protein functional studies have revealed new information about anaphase movement and the function of motor proteins.

Academic text (2009)
After the SAC is satisfied, anaphase is initiated.

Sliding of overlapping midzone microtubules to move apart the spindle poles (anaphase B).

Academic text (2009)
During anaphase, the chromosomes are pulled to opposite ends of the cell by the spindle fibers.
In a typical cell cycle, anaphase follows metaphase and is crucial for proper chromosome separation.
During anaphase, each sister chromatid is drawn towards the spindle poles, ensuring accurate cell division.

Surface Forms

anaphase singular

anaphases plural

Morphology

anaphase = phase (semi-transparent) = ana + phase

The component 'phase' (stage) is clear, but the combining form 'ana-' is technical and not familiar to general learners, so the specific biological sense is not fully inferable.

Etymology

Anaphase comes from the Greek parts ana- 'up' or 'back' and phase 'stage', and it uses the same idea of phase you know in English. So, anaphase is the stage in cell division when the chromosomes are pulled apart toward the two ends of the cell.
