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.
