(16) These findings, supported by simulation results, allow one to apply the theoretical results of the coalescence process directly to the allelic genealogy.
(17) This arose by the formation of large glycogen lakes, which coalesced and then lost their glycogen content, and this was accompanied by nuclear irregularity and shrinkage.
(18) Oil bodies isolated from mature maize (Zea mays) embryos maintained their discreteness, but coalesced after treatment with trypsin but not with phospholipase A2 or C. Phospholipase A2 or C exerted its activity on oil bodies only after the exposed portion of oleosins had been removed by trypsin.
(19) The ring-shaped elements of the RV and the moderately electron-dense material of the MDV were released exocytotically somewhat later; these materials coalesced in the perivitelline space to form a new coat (envelope 2).
(20) Following heated public debate over the issue of top-slicing the BBC licence fee, opinion at the broadcasters and the Department for Culture, Media and Sport is now coalescing around a less overt method of the corporation helping with Channel 4's future funding needs.
