Quizplus · Accepted Answer

Archaeans having multiple origins of replication is a characteristic that makes them more similar to eukaryotes than bacteria. Bacteria typically have a single origin of replication, while eukaryotes have multiple origins of replication on their chromosomes, allowing for the replication of their larger genomes. This feature in archaeans highlights the evolutionary relationship and similarities between archaeans and eukaryotes, despite archaeans being prokaryotic.
