At metaphase, chromosomes are attached to the spindle fibres by their (a) satellites (b) secondary constrictions (c) kinetochores (d) centromeres.
Option C The key feature of metaphase is the attachment of spindle fibres to kinetochores of chromosomes. Kinetochores are discshaped structures at the surface of the centromeres. These structures serve as the sites of attachment of spindle fibres to the chromosomes that are moved into position.
