Thermococcus, Methanococcus, and Methanobacterium exemplify
1 Archaebacteria that contain protein homologous to eukaryotic core histones
2 Archaebacteria that lack any histones resembling those found in eukaryotes but whose DNA is negatively supercoiled
3 Bacteria that contain a cytoskeleton and ribosomes
4 Bacteria whose DNA relaxed or positively supercoiled but which have a cytoskeleton as well as mitochondria
Explanation:
Thermococcus, Methanococcus, and Methanobacterium are examples for Archebacteria and they have different cell wall composition with polysaccharide and protein. They closely resemble eukaryotic cell in the mechanism like protein synthesis, structural protein and RNA compliments of the ribosomes.
