Аннотация

Anaphase chromatid behavior defects (CBDs) were quantitatively and qualitatively studied in nerve ganglion cells of third-instar larvae of several control wild-type Drosophila melanogaster strains and four strains with mutations of the aar(v158), ff3, mast(v40), and CycB(2g) cell-cycle genes. A linear specificity was observed for the CBD frequency, type, determination, and correction probability. The probability of anaphase CBD correction was close to unity in the control strains and lower in the mutant strains. The lower correction probability in the mutant strains was explained in the context of two findings, that the mutations induced the CBDs that were atypical of the wild-type strains and were potentially uncorrectable in anaphase and that the mutations negatively affected the relative anaphase time in mitosis.
