Comments

I-CreI has been used to generate a double strand breaks within the Ybb rRNA array (a degenerate consensus for the I-CreI endonuclease is present within the Ybb array): the size of the Ybb rDNA array in this chromosome is increased compared to the progenitor chromosome.

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.
    Phenotypic Data
    In combination with other aberrations

    The C(1)DX/Df(Y)l-539 combination (in which the Df(Y)l-539 chromosome is the only source of rDNA as C(1)DX lacks bb) is lethal.
