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 ...

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 ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, plays a ...

For foreign DNA to make it into a eukaryotic cell’s genome, DNA must first enter the cell, then cross the nuclear envelope, and finally insert itself into the genome. Below are a number of proposed ...

E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible. “It’s as ...
