|
Thermococcus, Methanococcus and Methanobacterium exemplify
|
archaebacteria that contain protein homologous to eukaryotic core histones
|
|
archaebacteria that lack any histones resembling those found in eukaryotes but whose DNA is negatively supercoilded
|
|
bacteria whose DNA is relaxed or positively supercoilded but which have a cytoskeleton and as well as mitochondira
|
|
bacteria that contain a cytoskeleton and ribosomes
|
Explanation:
Detailed explanation-1: -Thermococcus, Methanococcus and Methanobacterium belong to Kingdom Archeae. Archaea are prokaryotes and do not have a well-defined nucleus but they contain proteins homologous to eukaryotic core histones.
Detailed explanation-2: -Both Archaea and eukaryotes express histones, but whereas the tertiary structure of histones is conserved, the quaternary structure of histone–DNA complexes is very different.
