Sister chromatids are found in

Step-by-step solution

During metaphase, condensation of chromosomes is completed and they can be observed clearly under the microscope. This is the stage at which morphology of chromosomes is most easily studied. At this stage, metaphase chromosome is made up of two sister chromatids, which are held together by the centromere. Small disc-shaped structures at the surface of the centromeres are called kinetochores. These structures serve as the sites of attachment of spindle fibres (formed by the spindle fibres) to the chromosomes that ar
