Thermococcus, Methanococcus and Methano- bacterium exemplify

Question

Thermococcus, Methanococcus and Methano- bacterium exemplify (A) bacteria whose DNA is relaxed or positively supercoiled but which have a cytoskeleton as well as mitochondria (B) bacteria that contain a cytoskeleton and ribosomes (C) archaebacteria that contains protein homologous to eukaryotic core histones (D) archaebacteria that lack any histones resembling those found in eukaryotes but whose DNA is negatively supercoiled

Tardigrade Admin · Accepted Answer

Thermococcus, Methanococcus and Methanobacterium are archaea whose histones are shorter than eukaryotic histones and are assembled in tetramers. So the correct answer is' Archaebacteria that contain protein homologous to eukaryotic core histones'
