Supplemental Material

This article contains the following supporting material:

• Movie 1 - Dynamics of Mcp pairing. - P [Mcp, mini-white] elements were tracked by time-lapse microscopy. The line shown here carries inserts OM5 and OM7 located approximately at cytological positions 82-84 and 94-96 on chromosome 3. A total of 10 3-D stacks (20 sections each spaced at 0.25 micron intervals) were collected at 1 minute intervals. Videos 1-3 show three different nuclei.

• Movie 4 - Dynamics of Mcp pairing. - P [Mcp, mini-white] elements were tracked by time-lapse microscopy. The line shown here carries inserts OM5 and OM7 located approximately at cytological positions 82-84 and 94-96 on chromosome 3. Time lapse sequences consist of 240 frames, collected at 3 second intervals, for a total duration of 12 minutes and 6 seconds. Videos 4-6 show three different nuclei.
