Centromere identity must be maintained through multiple generations. A new study reveals a Constitutive Centromere-Associated Network (CCAN)-dependent retention of CENP-A, a key epigenetic mark for centromeres, in centromeres during DNA replication and a replication-dependent error correction to eliminate ectopic CENP-A in chromosome arms.
