The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes. The nucleus is made up of a double...
Learn about the nucleus in eukaryotic cells. Discover what a nucleus is, its structure, the function of the nucleus in eukaryotic cells, and the difference between eukaryotic cells and prokaryotic cells in terms of the nucleus. Updated: 11/21/2023 ...
The nucleolus is a well-known structure in the cell nucleus that is easily visible under a light microscope. This nuclear structure is known to be the site of ribosome production. A new study shows that the nucleolus is also a site of quality control for proteins. Whencellsare stressed, pro...
As it was pointed out during the opening lecture of the Workshop, we had several anniversaries in 2003, which are concerned with the cell nucleus. The 50 years of the double helix paper have been celebrated all over the world, but two others are worth mentioning: the paper by Cogliati ...

As such, the nucleus consists of a number of structured elements that allow it to perform its functions. This section gives focus to the structure of the cell.In general, the nucleus has a spherical shape as shown in most books. However, it may appear flattened, ellipsoidal or irregular ...
