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 ...

Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.

Protection of Genetic Material: The nuclear envelope shields the DNA from the mechanical and chemical stresses of the ...

All living organisms are made up of cells. It is the basic, structural, and functional unit of life. Also, it is known as "Building blocks of life". Cell biology is the study of cells. It consists of ...

Unlike their simpler prokaryotic counterparts, eukaryotic cells boast a complex internal architecture. This complexity stems ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...

The faithful replication of chromosomes relies on evolutionarily conserved initiator proteins to recruit ring-shaped helicases to DNA in a cell-cycle-regulated manner (reviewed in refs 1, 2, 3).
