The Cd technique identifies a specific structure related to centromeric function.
The evidence that the Cd technique identifies the kinetochore was based on the finding that inactive centromeres are C-positive but Cd-negative. The identity between Cd-positivity and centromere function is now confirmed by the reverse procedure: a stable abnormal chromosome is consistently C-negative but Cd-positive at its single centromeric constriction. This demonstrates that the Cd dots are not a relic of C-banding but identify the active centromere.
