All genes critical for plasmid replication regulation are located on the plasmid rather than on the host chromosome.It is possible therefore that there can be copy-up "cheater" mutants.In spite of underwater treasures sunken medallion this possibility, low copy number plasmids appear to exist stably in host populations.We examined this paradox usin
Numerous dromaeosaurid taxa recovered from the Upper Cretaceous strata of the Gobi Desert raise questions over niche partitioning among closely related species.Here, I describe a dromaeosaurid specimen from the Baruungoyot strata of the Khulsan locality, containing a partial skull in close association with the left hind limb.The material can be ref
