In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes ...

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 ...

Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is ...

Cells somehow evolved from primordial chemistry and their emergence depended on the co-evolution of the cytoplasm, a genetic system and the cell membrane. It is widely believed that the cytoplasm ...

A new idea about the origin of complex life turns current theories inside out. Scientists explain their 'inside-out' theory of how eukaryotic cells, which all multicellular life -- including us -- are ...

An exchange of genetic material that occurred when ancient giant viruses infected ancient eukaryotic cells could have caused the nucleus of the eukaryotic cell -- its defining feature -- to form. A ...

Phalloidin, the toxic drug from the mushroom Amanita phalloides, was injected into the cytoplasm of tissue culture cells and the changes in intracellular actin distribution were followed by ...

Perhaps as far back as the history of research and philosophy goes, people have attempted to unearth how life on earth came to be. In the recent decades, with exponential advancement in the fields of ...
