Basic structural and functional unit of life forms.
Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic cells, which do not have a nucleus, but a nucleoid region is still present.
Eukaryote
23 linksEukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Protein
18 linksProteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
In contrast, eukaryotes make mRNA in the cell nucleus and then translocate it across the nuclear membrane into the cytoplasm, where protein synthesis then takes place.
Gene
16 linksBasic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
Basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
The chromosomes are packed within the nucleus in complex with storage proteins called histones to form a unit called a nucleosome.
Mitochondrion
15 linksDouble-membrane-bound organelle found in most eukaryotic organisms.
Double-membrane-bound organelle found in most eukaryotic organisms.
Although most of a cell's DNA is contained in the cell nucleus, the mitochondrion has its own genome ("mitogenome") that is substantially similar to bacterial genomes.
Bacteria
20 linksBacteria (singular bacterium, common noun bacteria) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Bacteria (singular bacterium, common noun bacteria) are ubiquitous, mostly free-living organisms often consisting of one biological cell.
Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles.
Cytoskeleton
10 linksComplex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, excluding bacteria and archaea.
Complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, excluding bacteria and archaea.
It extends from the cell nucleus to the cell membrane and is composed of similar proteins in the various organisms.
Nuclear pore
11 linksA nuclear pore is a part of a large complex of proteins, known as a nuclear pore complex that spans the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus.
Cytoplasm
10 linksIn cell biology, the cytoplasm is all of the material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus.
Gene expression
13 linksProcess by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.

In eukaryotes most mature RNA must be exported to the cytoplasm from the nucleus.
