cell - (biology) the basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals
pronucleus - the nucleus of the ovum or sperm after fertilization but before they fuse to form the nucleus of the zygote
karyoplasm, nucleoplasm - the protoplasm that constitutes the nucleus of a cell
nucleole, nucleolus - a small round body of protein in a cell nucleus; such organelles contain RNA and are involved in protein synthesis
chromatin, chromatin granule - the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division it condenses into chromosomes
achromatin - the part of a cell nucleus that is relatively uncolored by stains or dyes
linin - an obsolete term for the network of viscous material in the cell nucleus on which the chromatin granules were thought to be suspended
chromosome - a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order; "humans have 22 chromosome pairs plus two sex chromosomes"
cell organ, cell organelle, organelle - a specialized part of a cell; analogous to an organ; "the first organelle to be identified was the nucleus"

The study, which also included Fang-Yi Chu, an NYU doctoral candidate, and Shannon Haley, an NYU undergraduate, sought to expand our understanding of the cell nucleus during the cell cycle.
It integrates to and inhibits the nuclear export protein XPO1, resulting in the accumulation of tumour suppressor proteins in the cell nucleus.
Mitosis is a part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
The new patent application is based on the ability of HDAC6 inhibitors to influence mechanisms both inside and outside of the cell nucleus. It has been shown that the major biological roleof HDAC6 is in the regulation of the cancer cell[acute accent]s ability to migrate and form metastases.
Karine Le Roch, an associate professor of cell biology and neuroscience, who led the study and her research team also found that those genes that need to be highly expressed in the malaria parasite - for example, genes involved in translation - tend to cluster in the same area of the cell nucleus, while genes that need to be tightly repressed - for example, genes involved in virulence - are found elsewhere in the 3D structure in a "repression center."
Contributors from a wide range of biological sciences and medical specialties review recent developments in the knowledge and understanding of structures and functions of the cell nucleus in plants, including that of the nuclear envelope.
In EMN method, electric field exposure induced an increase in electrophoretic mobility of cell nuclei (EMN index), decreased numbers of heterochromatin granules near the inner membrane of cell nucleus, and induced cell membrane damage; but cell viability was conserved.
