We show that 18S sequences are more homogenous than ITS1; a pattern that could arise from incomplete rounds of homogenisation and stronger purifying selection acting on the 18S genic region.
After shooting a three-under-par 69 in yesterday's incomplete opening round, Haas was only two strokes behind the clubhouse leader, Justin Rose of England, prompting the natural question: if Jack Nicklaus in 1986 was the oldest at 46 to win at Augusta National, can a 50-year-old win the Masters?
Maybe we really do still need journalists, maybe articles really don't write themselves... but realistically, it seems difficult to draw any conclusions from a badly researched, hastily coded and all round incomplete investigation.
We observed myocyte polyploidy in control hearts and increases in myocyte ploidy in the RafAct hearts that is suggestive of incomplete endocycling, repetitive rounds of genome replication.
In e-mail, he is sharp and funny and occasionally strident, but in person he's nearly the opposite: hesitating to name or quantify very much, rounding off incomplete thoughts with quick, conciliatory grins.
Therefore, syncytial cysts derived from more than four rounds of incomplete cell divisions are the more parsimonious explanation.
Firstly, germ cells in cysts that have undergone the usual four rounds of incomplete cell division can have at most four ring canals [9], [10] (Fig. 3F).
In region 1, the germline stem cell (GSC) divides to produce a cystoblast, which undergoes four rounds of incomplete cell division to produce a 16-cell interconnected cyst.
A single GSC division gives rise to a cystoblast, which undergoes four rounds of incomplete division to form a 16-cell cyst; the cells of the cyst are interconnected with branched fusomes (Spradling, 1993).
In the choanoflagellate Salpingoeca rosetta, rosette-shaped multicellular colonies develop when a single founder cell undergoes multiple rounds of incomplete cytokinesis, leaving neighboring cells physically attached by fine intercellular bridges (Fairclough et al. 2010; Dayel et al. 2011).
