- Abstract. The cell nucleus is a double membrane‐bound organelle that contains the genetic information of the cell packaged in the form of chromatin.The nucleus is a characteristic feature of most eukaryotic cells.The nucleus is considered to be one of the most important structures of eukaryotic cells as it serves the function of information storage, retrieval and duplication of genetic information.he cell nucleus contains nonmembranous distinct substructures that are characterised by having a specific subset of proteins and RNA. The nuclear envelope is a highly regulated membrane barrier that allows the compartmentalisation of the nucleus from the cytoplasm.

The Cell Nucleus The Cell Nucleus: The cell nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is the command center of a eukaryotic cell and is commonly the most prominent organelle in a cell. Distinguishing Characteristics. The cell nucleus is bound by a double membrane called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm. Like the cell membrane, the nuclear envelope consists of phospholipids that form a lipid bilayer.

Atomic nucleus The nucleus is the centre of an atom. It is made up of nucleons (protons and neutrons) and is surrounded by the electron cloud. The size (diameter) of the nucleus is between 1.6 fm (10 −15 m) (for a proton in light hydrogen) to about 15 fm (for the heaviest atoms, such as uranium).

Cell nucleus In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel) is a membrane-enclosed organelle found in eukaryotic cells.Eukaryotes usually have a single nucleus, but a few cell types have no nuclei, and a few others have many.he nucleolus is a discrete densely stained structure found in the nucleus. It is not surrounded by a membrane, and is sometimes called a suborganelle. It forms around tandem repeats of rDNA, DNA coding for ribosomal RNA (rRNA). These regions are called nucleolar organizer regions (NOR).

Median preoptic nucleus These include osmoregulation, thermoregulation, and sleep homeostasis. Within each area are many functions. The role that the median preoptic nucleus plays in osmoregulation is in blood composition and volume, including fluid and salt balance, and produces responses ranging from behavioral to endocrine.

Cell Nucleus and Nuclear Envelope While the DNA remains in the nucleus, it controls most of the processes that occur in the cytoplasm of the cell. Information from the DNA can be transcribed to mRNA and transmitted to other cellular synthesis processes, and information from the cytoplasm can provide feedback to the nucleus.The nucleolus is the central portion of the cell nucleus and is composed of ribosomal RNA, proteins and DNA.It also contains ribosomes in various stages of synthesis.

- Plant Cell Nucleus The nucleus is a highly specialized organelle that serves as the information and administrative center of the cell. This organelle has two major functions.It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.ucleolus-The nucleolus is a membrane-less organelle within the nucleus that manufactures ribosomes, the cell's protein-producing structures. Through the microscope, the nucleolus looks like a large dark spot within the nucleus.

Nucleic-acid-chaperone activity of retroviral nucleocapsid proteins: significance for viral replication Abstract. Retrovirus particles contain a small, basic protein, the nucleocapsid (NC) protein, that possesses `nucleic acid chaperone' activity-that is, the NC protein can catalyze the rearrangement of a nucleic acid molecule into the conformation that has the maximal number of base pairs.he mechanism behind nucleic-acid-chaperone activity has also been investigated by testing the activity of mutant NC proteins, and a number of different assays have been used. These studies have shown that the highly basic character of the NC protein is essential for its activity.
