The quality and value of freshwater nonnucleated
pearls depend on the characteristics of pearl size, color, shape, luster, and surface.
It is at work in every "major transition" in evolution: from single replicators to ensembles of genes, from nonnucleated
to nucleated single-cell organisms, from single-cell organisms to multi-cellular organisms, and from isolated individual organisms to social organisms (Bowles and Gintis, Cooperative Species; Calcott and Sterelny; Haidt; Maynard Smith and Szathmaary; Michod; Simpson).
They are nonnucleated
and possess little viable mitochondria, glycogen, many types of morphologically variant granules (dense core granules and lysosomes), and a complex membranous system.
Platelets are small nonnucleated
blood cells that have a vital role in hemostasis and thrombosis and are produced in the bone marrow from megakaryocytes.
We used a hemocytometer with trypan blue exclusion to obtain total cell counts (excluding nonnucleated
4 for nucleated and nonnucleated
54) He describes a method for removing mitochondrial DNA and replacing it with the mitochondria from platelets, creating a combination of nucleated and nonnucleated
cells called cybrids.
Reticulocyte counts are based on identification of residual ribosomes and RNA in immature nonnucleated
red blood cells (RBCs).
The cyst wall consists of an inner nucleated germinative layer and an outer nonnucleated
proteinaceous layer, which is laminated.
