Chromatids Draw Annotate Describe Occurs Anaphase Centromeres Holding

In anaphase, centromeres divide, separating sister chromatids which are pulled to opposite poles by spindle fibers.

During anaphase, the centromeres divide, and sister chromatids are pulled apart by shortening spindle fibers to opposite poles of the cell.

Front Draw, annotate and describe what occurs during anaphase.
Back Anaphase:
  • Centromeres holding pairs of chromatids in each chromosome divide
  • Chromatids separated - pulled to opposite ends by shortening of spindle fibers
