Fig. 2. Dictyostelium heterochromatin is late replicating.
(A) Localisation of RFP-PCNA and heterochromatin (HcpB) and nucleolar
(eIF6) markers. Right-hand panels show merged images. (B) Localisation
of PCNA and HcpB after mitosis. The HcpB spot is assembled then recruits
nucleoplasmic PCNA. Arrows indicate the times at which HcpB and PCNA spots
become visible.
