At least two separate clusters of Bari1 repeats exist in the h39 region.
Bari1 elements are unstable in Charolles stock. Instability is persistent over 53 generations and appears to affect recurrent insertion
sites.
By comparing methylation by Ecol\dam methylase between euchromatic and heterochromatic genes it was determined that the heterochromatic state does not prevent
methylase accessibility in vivo.
Bari1 is widespread in the genus Drosophila.
The distribution of transposable elements within heterochromatin indicates that they are major structural components of the
heterochromatin.
The 1.7kb Bari1 element makes up a middle repetitive DNA family that shows many characteristics in common with transposable elements, though
its mobility has not yet been demonstrated. Most copies are homogeneously clustered with a unique location close to the centromere
of the second chromosome, and all copies have the same open reading frame.
