Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure ... may have originated (Poole & Penny 2007). One of these involves fusion between cells from ...

This makes it a critical part of prokaryotic cell function. Prokaryotes do not have mitochondria. Interestingly, one widely accepted theory of eukaryotic evolution, known as the endosymbiotic theory, ...

The origin of eukaryotes is considered one of the greatest enigmas in ... for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future gene-editing ...

All ribosomes (in both eukaryotic and prokaryotic cells) are made of two subunits — one larger and one smaller. In eukaryotes, these pieces are identified by scientists as the 60-S and 40-S ...

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

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 ...

Most prokaryotes have single circular genomes and reproduce asexually, which means when the time comes for their cells to divide, they simply have to copy their circular genomes and make sure one ...

One product of photosynthesis ... it still shares a world teeming with successful prokaryotic life forms. Rather, our interest in eukaryotes is because this type of cell is the basis of our ...
