Abstract:
We studied the cytogenetic effect of P[lArB] transposon insertion into the 42A region of the second D. melanogaster chromosome (mutation 22w). This mutation was shown to induce metaphase (rarer anaphase) block of the cell cycle. The chromosomes have an abnormal "lump" morphology. Possible involvement of the corresponding gene product in functioning of the cell oscillator is discussed.
