Comments

An attP attachment site is first targeted distal to the most distal essential gene mod on chromosome 3R via homologous recombination. A fragment consisting of a 240-copy tandem repeat of lacO sites together with a proximal y marker and a distal I-SceI recognition site is integrated at the attP site next. Subsequently, sequences distal to the I-SceI recognition site including Map205 are deleted creating an artificial telomere marked with an lacO-array.

Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
