DNA Organization of Methanobacterium thermoautotrophicum

The organism Methanobacterium thermoautotrophicum, an archaebacterium, is evolutionarily very distant from both traditional prokaryotes and eukaryotes. Its genome (DNA) has physical characteristics typical of most prokaryotes except that it is quite small (about 10$^{9}$ daltons, less than half the...

Summary:The organism Methanobacterium thermoautotrophicum, an archaebacterium, is evolutionarily very distant from both traditional prokaryotes and eukaryotes. Its genome (DNA) has physical characteristics typical of most prokaryotes except that it is quite small (about 10$^{9}$ daltons, less than half the size of the genome of Escherichia coli) and contains a significant amount (6 percent) of DNA which renatures extremely rapidly.
