Structural Biochemistry/Cell Organelles/Nucleus The nucleus is a membrane-enclosed organelle found in eukaryotic cells. It contains the genetic material of the cell, organized as multiple long linear DNA molecules that coil around to form chromosomes.The transcription of RNA also takes place in the nucleus.he Nucleus [edit]. Eukaryotes derive their name from the fact that they contain a nucleus. The nuclus is also often the most prominent feature of eukaryotic cells viewed under a microscope. The nucleus is an organelle, an intracellular membrane-enclosed compartment with a specific function.

What does nuclei mean? (Biology))? Report Abuse. a nucleus (nucleii refers to more than one nucleus, it is the plural form of the word nucleus) is a core, the central and generally key or most important thing to the total structure. A nucleus, when discussing cells, is the area of the cell where genetic material resides. It has its own structural border (a semi-permeable wall separating it from the main cell mass). You must know what a cell nucleus is without needing further detail. It is a fairly basic term to cell biology.

Why Orangutans Are Endangered For the two species of orangutans found on the islands of Sumatra and Borneo in southeast Asia, mature tropical rainforests are essential to their survival. Orangutans live entirely in trees. The reason why orangutans are endangered can be summed up with two words: habitat loss.he number of orangutans on Borneo dropped by over half in the last 60 years. On Sumatra, the orangutan population is just one-fifth of what it was 75 years ago. Sumatran orangutans are the most endangered great ape in the world. Unfortunately, their future is bleak.

- 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 Nucleus The atomic nucleus consists of nucleons—protons and neutrons. Protons and neutrons are made of quarks and held together by the strong force generated by gluon exchange between quarks. In nuclei with many nucleons, the effective strong forces may be described by the exchange of mesons (particles composed of quark-antiquark pairs). A proton consists of two up quarks and one down quark along with short-lived constituents of the strong force field. A neutron is similar except that it has two down quarks and one up quark. Although scientists are convinced that nucleons are composed of quarks, a single quark has never been isolated experimentally. Energy brought into a nucleus to try to separate quarks increases the force between them.

What holds nucleons together in a nucleus? Hi To be precise, STRONG FORCES holds nucleus together. As kids, we learn about nucleus and also that like charges repel each other. if thats the case, then why dont protons inside nucleus , bound so close to each other and to neutrons, explode instead of binding so close to each other that giving density to nucleus that of 100000 times more than the density of iron. reason 1. protons and neutrons are ALIKE inside a nucleus. meaning they work independent of charges. they are no more neutral ...

Cell nucleus Eukaryotes usually have a single nucleus, but a few cell types have no nuclei, and a few others have many. Cell nuclei contain most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes.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).

Difference Between Nucleus and Nucleolus There are a few differences between the nucleus and nucleolus. To better differentiate the two parts of the cell, we should consider the functions, structures, and other features of these cellular organelles. Basically, the nucleolus is just a part of the nucleus.The nucleus is the main part of the cell while the nucleolus is part of the nucleus itself. The nucleus is a membrane-bound organelle that is found in multi-celled organisms or eukaryotes.This membrane that encloses the nucleus has two parts. The parts of the membrane are the inner and outer cellular membrane..The nucleus is membrane bound while the nucleolus is non-membrane bound. 3.The nucleus contains DNA while the nucleolus contains RNA. 4.The nucleus has the chromosomes and cellular membranes while the RNA has the fibrillar centers, dense fibrillar centers, and the granular component.
