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 ...
Endosymbioses have dramatically altered eukaryotic life, but are thought to have negligibly affected prokaryotic evolution. Here, by analysing the flows of protein families, I present evidence that ...
DNA methylation refers to the process of adding a methyl group to specific regions of DNA. This process can bring about changes in the activity of DNA without changing the sequence of nucleotides.
