What is Nucleoplasm? Nucleoplasm, also called nuclear sap or karyoplasm, is the fluid usually found in the nucleus of eukaryotic cells.This fluid contains primarily water, dissolved ions, and a complex mixture of molecules. Its primary function is to act as a suspension medium for the organelles of the nucleus.ucleoplasm is the fluid found in the nucleus of eukaryotic cells. When chromatin is suspended in the nucleoplasm, it condenses during cell division to form chromosomes.

Cell Nucleus and Nuclear Envelope 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. The nucleolus accomplishes the manufacture of the ribosomes.he nuclear envelope surrounds the nucleus with a double membrane with multiple pores. The pores regulate the passage of macromolecules like proteins and RNA, but permit free passage of water, ions, ATP and other small molecules.

Nucleolus The nucleolus is contained within the cell nucleus. A nucleolus (plural: nucleoli) is the part of a eukaryote cell where ribosomes are made. Viewed through a microscope, the nucleolus appears as a dark spot inside the cell's nucleus. It is made up of dense RNA and proteins.here is usually more than one nucleolus in a eukaryote cell. The nucleolus is made at a nucleolus organizer region (NOR), which is a chromosome region around which the nucleolus forms. Inside the nucleolus ribosomes are made. Ribosomes are molecular machines that synthesize proteins.

Extrachromosomal DNA Extrachromosomal DNA is any DNA that is found outside the nucleus of a cell. It is also referred to as extranuclear DNA or cytoplasmic DNA. Most DNA in an individual genome is found in chromosomes but DNA found outside the nucleus also serves important biological functions. In prokaryotes, nonviral extrachromosomal DNA is primarily found in plasmids whereas in eukaryotes extrachromosomal DNA is primarily found in organelles. Mitochondrial DNA is a main source of this extrachromosomal DNA in euka
