The chromosome number in cells may be haploid, with one set of chromosomes per cell (written 1n); diploid, with two sets (2n); polyploid, with three or more sets; or dikaryotic, with a pair of nuclei in a cell (n + n), a condition that occurs mainly in fungi.
The amount of matter involved in the RHIC collisions is "exceedingly small--only a single pair of nuclei is involved in each collision," he noted.
Once the database from a specific network is built and stored in a file, routines of this system can be used to classify the nuclei in term of their afferents and efferents and also to display all possible pathways linking any pair of nuclei and their respective length (number of synapses).
The SCN is composed of a pair of nuclei, each of which is comprised of 8,000 neurons approximately [4], [5].
A more ancient case of subcellular relocalization is a pair of nucleus-encoded organellar ribosomal protein genes (Rps13) in rosids where one is localized to the chloroplast and the other has been relocalized to the mitochondria (Adams et al. 2002; Mollier et al. 2002).
Karyotyping of the isolates showed single or pair of nuclei within the hyphae.
During the migration of the two pairs of nuclei to the opposite poles, the four-nucleate embryo-sac tends to take a "J" shape.
Aromaticity has a vast history in chemistry, and it is still a very active and unfolding history because of the problems, to our understanding, posed by electrons that seem to be circulating around a whole molecule rather than localized between pairs of nuclei.
Restraints on distances between pairs of nuclei in the protein, derived from the nuclear Overhauser effect (NOE), provide information about the structure of the protein in its folded state.
With loss of separase activity, microtubule arrays emanate from the nuclei asymmetrically, with dense accumulation between certain pairs of nuclei and little or no accumulation between others.
This procedure does not make any assumption about the distribution of the test statistic and takes into account that the distances between different pairs of nuclei on the egg surface are not independent from each other.
