Are bacterial chromosomes mobile genetic elements?

2021_images/Hall_etal_Nat_Comm.png Read the Evo GoodReads digest!
Horizontal gene transfer among chromosomal genes in bacteria can exceed that of mobile genetic elements such as plasmids. This observation suggests bacterial chromosomes should be thought of as mobile genetic elements.
