Summary Introduction
To review:
The findings that led to the establishment of bacteria and archaea as separate domains.
Introduction:
All living organisms in the universe share various characters with each other. Despite the fact, there are many differences in their characters, which form the diversity of life. Nowadays, scientists have differentiated organisms with the help of genome sequencing. This genome sequencing first proved that there are two main divisions of life—bacteria and archaea. These two divisions are a part of prokaryotes.
