Summary Introduction
To review:
The archaeal features that share genetic similarities with bacteria and the features that share similarities with eukaryotes.
Introduction:
A comparison of archaeal genes with bacteria and eukaryotes have revealed that they share genetic similarities with both of these groups. This provides evidence for the evolutionary relationship between the groups. Some features of archaeal genome structures are unique while some traits are similar to prokaryotes and others resemble to that of eukaryotes.
