My primitive understanding is that the bottleneck for bacterial reproduction is DNA replication, so there’s a huge incentive to shed unneeded DNA, especially with mechanisms to get genes back via HGT. Am I right in thinking that the more efficient chromosome replication in eukaryotes doesn’t penalize junk dna the same way, so it can just stick around?
