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 ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

A nucleus is one of many membrane-bound compartments that distinguishes our eukaryotic cells from the prokaryotic cells of microorganisms like bacteria. Eukaryotic cells also possess energy-producing ...

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning “true kernel”) have a cell nucleus that harbours most of the cell’s genetic information and ...

All complex life forms on Earth, including plants and animals, are made up of eukaryotic cells; they are more sophisticated than bacterial or archaeal cells, which are prokaryotic. Eukaryotes have ...

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, ...
