The dynamic organization of prokaryotic genomes: DNA bridging and wrapping proteins across the tree of life
Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.
