CENP-A containing chromatin assembly obsolete centromere complex assembly https://github.com/geneontology/go-ontology/issues/30209 true chromosome, centromeric region assembly centromere organization This term was obsoleted because it is an unnecessary grouping term. GO:0034508 OBSOLETE. The aggregation, arrangement and bonding together of proteins and centromeric DNA molecules to form a centromeric protein-DNA complex. Includes the formation of the chromatin structures which form a platform for the kinetochore, and assembly of the kinetochore onto this specialized chromatin. In fission yeast and higher eukaryotes this process also includes the formation of heterochromatin at the outer repeat (pericentric) regions of the centromere. biological_process centromere assembly kinetochore assembly
