Fig. 2. Densities (gold particles/µm²) on the FC, DFC, GC and resin (R) in nucleoli isolated from ELT cells and incubated with BrUTP for 1 to 25 minutes. The results shown represent mean values±s.e.m. 7, 14, 13 and 12 random micrographs were analyzed and 51, 120, 211 and 274 gold particles were counted, respectively. Student's t-test for nucleolar components versus resin (+ P<0.05, ++ P<0.01) and for FC versus DFC in different pulse-labelled nucleoli (^ P<0.05, ^^ P<0.01) was used.
