Sorry, no etymologies found.
The plasmid must contain prokaryotic nucleotide sequences coding for a bacterial replication origin for DNA and an antibiotic resistance gene.
Indeed Dulbecco's laboratory was filled with first-class postdoctoral fellows from around the world, who were trained in prokaryotic molecular biology and who came there intending to expand their research into eukaryotic molecular biology.
Most large-scale genomic studies suggest that the answer is an archaeon - that is, a prokaryotic cell that is in most respects like a bacterium.
I’d also like an explanation for the following: Among the 21 proteins in the small subunit, 13 proteins were identified as prokaryotic homologues and eight proteins were specific to the mammalian mitoribosome Table I.
"prokaryotic" cells-which lack cell nuclei-evolved differently from that of "eukaryotic" cells with nuclei that comprise most other forms of life, from fungi to plants and animals.
The cases in point include the origin of complex RNA molecules and protein folds; major groups of viruses; archaea and bacteria, and the principal lineages within each of these prokaryotic domains; eukaryotic supergroups; and animal phyla.
Life was prokaryotic and unicellular for 3 billion years.
During the Archean Eon life started and was dominated by one-celled prokaryotic life forms.
Martian life, should it exist, is not likely to be much more than prokaryotic-like forms making a living in the soil or in little niches free from solar UV and where they can catch a bit of water now and then.
Note that since the typical human eukaryotic cell probably has around 100 times or so the volume and mass of a typical human-inhabiting prokaryotic bacterial cell, we are still probably more human than bacteria on a biomass basis.
