A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

The basic building blocks of all living things are cells. The body of humans is made up of trillions of cells. Plants and animals are made up of cells. They are considered as the basic units of life.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

For more than 30 years, scores of reports have provided evidence for the presence of actin in the nucleus, but until recently the functional significance and even the validity of these findings was in ...

A novel pathway by which proteins are actively and specifically shuttled into the nucleus of a cell has been discovered by scientists. The finding captures a precise molecular barcode that flags ...

The architecture of cell nuclei is often altered in cancer cells. Specific tumour types are associated with characteristic alterations, and these provide an important diagnostic feature. The nuclear ...

Light can be used to control the transport of proteins from the cell nucleus with the aid of a light-sensitive, genetically modified plant protein. Biologists working in the field of optogenetics have ...

Tim Mercer receives funding from the NHMRC and ARC. He is affiliated with the Garvan Insitute for Medical Research, and the University of Queensland. When scientists first decided to sequence the ...

Researchers at the Francis Crick Institute have shown that the "pacemaker" controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

Bone implants often fail to fully integrate with surrounding tissue, limiting their effectiveness in regeneration. A natural but often overlooked cellular process could hold the key to better outcomes ...

Because viruses have to hijack someone else’s cell to replicate, they’ve gotten very good at it—inventing all sorts of tricks. A new study from two University of Chicago scientists has revealed how ...
