The spindle fiber begins to form
Webspindle fibers. Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into … WebA) DNA condenses to form chromosomes B) nuclear membrane breaks down C) nucleolus breaks down D) chromosomes are replicated E) mitotic spindle begins to form D chromosomes are not replicated The mitotic spindle fibers attach to chromosomes via special structures termed A) centrioles.
