organelle

 [or″gah-nel´]
any of the organized cytoplasmic structures of distinctive morphology and function present in all eukaryotic cells, including such structures as the nucleus, mitochondria, lysosomes, peroxisomes, Golgi apparatus, and endoplasmic reticulum, as well as chloroplasts in plants and cilia and flagella in protozoa.

or·gan·elle

(or'găn-el),
One of the specialized parts of a protozoan or tissue cell; these subcellular units include mitochondria, the Golgi apparatus, nucleus and centrioles, granular and agranular endoplasmic reticulum, vacuoles, microsomes, lysosomes, plasma membrane, and certain fibrils, as well as plastids of plant cells.
Synonym(s): cell organelle, organoid (3)
[G. organon, organ, + Fr. -elle, dim. suffix, fr. L. -ella]

organelle

(ôr′gə-nĕl′)
n.
A differentiated structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function.

or·gan·elle

One of the specialized parts of a protozoan or tissue cell; mitochondria, the Golgi apparatus, nucleus and centrioles, granular and agranular endoplasmic reticulum, vacuoles, microsomes, lysosomes, plasma membrane, and certain fibrils, as well as plastids of plant cells.
Synonym(s): organoid (3) .
[G. organon, organ, + Fr. -elle, dim. suffix, fr. L. -ella]

organelle

Any one of the bodies forming the internal functional components, or ‘little organs’, of the cell. The organelles include MITOCHONDRIA, the GOLGI APPARATUS, the ENDOPLASMIC RETICULUM, RIBOSOMES, LYSOSOMES and the CENTRIOLES.

organelle

any part of a cell that has a particular structural or functional role, such as FLAGELLUM or a MITOCHONDRION. Organelles are analogous with organs in the body of multicellular organisms.

Organelle

Specialized structure within a cell, which is separated from the rest of the cell by a membrane composed of lipids and proteins, where chemical and metabolic functions take place.

This rearrangement of organelles could be mediated through the dynamic filaments of cytoskeleton contraction towards the periphery in close proximity of cell membrane during M-phase and relaxation would bring back post-mitotically to the normal setting of organelles in daughter cells.
That caused SPOP and DAXX to move from their location in separate membraneless organelles in the nucleus and rendezvous to form their own border-less compartment.

This is achieved using a combination of engineering and/or selection of strains which: do not express certain enzymes which create the undesirable complex structures characteristic of the fungal giycoproteins, which express exogenous enzymes selected either to have optimal activity under the conditions present in the fungi where activity is desired, or which are targeted to an organelle where optimal activity is achieved, and combinations thereof wherein the genetically engineered eukaryote expresses multiple exogenous enzymes required to produce "human-like" glycoproteins.
