From: Sequence signature analysis of chromosome identity in three Drosophila species
Localisation and mapping of POF on salivary gland F-element in Dm. (A) F-element stained with DAPI, showing cytological map positions. (B) F-element stained with anti-POF antibody. White lines indicate regions with weak POF staining. (C) Number of nonamers (grey) and nonamer pairs (black) per 10 kbp. The x-axis scale is in 100 kbp. White areas indicate regions of weak POF staining seen in (B). The sequence positions of the polytene chromosome bands are according to Dm annotation release 3.2. The genomic sequence 1 to 830 kpb shown in (C) corresponds to cytological region 102A to 102E5.
