UASt regulatory sequences drive expression of an inverted repeat.
The expression of cidKK110670 under the control of Scer\GAL4VP16.bam leads to a significant increase in the number of centrosomes in early prophase I (S1/2a), late prophase (S5/6) and prometaphase I spermatocytes, but not in spermatocytes in interphase, as compared to controls; there are no significant changes in sister chromatid arm cohesion in S5/6 spermatocytes.
