Fig. 3. Swellings in the distal part of the chromosome 2R of Oregon R control stock (A) and SuUR⁺/SuUR⁺ Sgs3-GAL4 UAS-SuUR⁺ young larvae (B), late larva (C) and late prepupa (D). The chromosome shown in E was taken from prepupa that developed till the 0 hours prepupal stage at 29°C followed by a 15 hour development at 18°C. Asterisks in A mark regions of late replication.
