A myofiber was considered INF if at least one nucleus was non-peripheral.
Some galaxies can have more than one nucleus.
All of tissue punches from one nucleus of one bird were pooled, flash frozen in dry ice, and stored at –80 °C until processed for microarray hybridization.
Furthermore, in an optimal standard cross section (5 10 µm) binucleated cells cannot be detected, because usually only one nucleus is sectioned at a time.
The genetic materials from the sperm and the egg have not yet fused to form one nucleus; rapid demethylation at this stage could therefore not result from replication, thus suggesting an alternative active demethylation pathway.
However, after the one nucleus stage, eggs with 2, 4, 8, 16 and 32 nuclei at the surface were found in the uteri of different females (Fig. 3A G).
But when the nucleus divides, one nucleus makes its way to the other end of the sac.
Cells with one kinetoplast and one nucleus (1K1N) are in G1 of the cell cycle, cells with two kinetoplasts and one nucleus (2K1N) have segregated the kinetoplast and are at the end of S phase, and cells with two kinetoplasts and two nuclei (2K2N) have completed mitosis and are poised for cytokinesis [ 46].
With reference to recent studies reporting on the various biological properties of the thiazolidinone scaffold, we synthesized more than a hundred compounds characterized by a 1,3-thiazolidin-4-one nucleus derivatised at the C2 with a hydrazine bridge linked to (cyclo aliphatic or hetero aryl) moieties, and their N-benzylated derivatives.
During the initial 6 8 days of culture at 18°C, the cell population in culture was predominantly composed of large oval cells which displayed three nuclei similar to mature pollen, as revealed by DAPI staining, two small nuclei similar in size and fluorescent brightness (sperm like nuclei) and one large nucleus (vegetative like nucleus) with faint fluorescence.
