Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

The origin of the eukaryotic cell remains one of the most contentious puzzles in modern biology. Recent studies have provided support for the emergence of the eukaryotic host cell from within the ...

But what if I were to tell you that there are just two kinds of organisms? According to scientists, the world is split into two kinds of organisms — prokaryotic vs. eukaryotic — which have two ...

Amoeba are more closely related to humans than to bacteria, at least in the tree of life. Like mammals, they belong to the realm of the eukaryotes, while bacteria are prokaryotes. The first eukaryotes ...

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 ...

Protein synthesis refers to the process by which cells construct proteins. It's a fundamental cellular mechanism for all ...

Recent discoveries are revealing how the first eukaryote got its start. Three billion years ago, life on Earth was simple. Single-celled organisms ruled, and there wasn’t much to them. They were what ...

Daniel Mills, Ludwig-Maximilians-Universität München During this time, some of the defining characteristics of modern eukaryotic cells—the nucleus, mitochondria, cytoskeleton, cell membrane, and ...
