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 ...

IN his presidential address to the Royal Microscopical Society delivered on Jan. 20, Prof. R. Ruggles Gates reviewed present knowledge regarding nuclear structure, especially in relation to genetics.

For decades the cell nucleus has been a black box of biology—scientists have understood little about its structure or the way it operates. But thanks in part to new visualization technologies, ...

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 discovery of giant viruses has changed what we thought we knew about microbes. Researchers have now learned more about giant viruses that can infect bacterial cells, so-called jumbo phages.

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 ...

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 ...

The discovery of a defensive mechanism could help stop cancer before it spreads. Cancer cells rapidly increase their energy ...

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 ...
