Time-lapse images of dynamic astral microtubules in a mock-treated (DMSO) HU-arrested (S-phase) Tub3-only cell with microtubules labeled with GFP-Tub1 and their plus ends enhanced with Bik1-3GFP. Images were captured at 8-s intervals and represent composite maximum projections of 10 z-planes spaced 0.75 µm apart. Video plays at 10 fps and encompasses 9.3 min.
