Web9 apr. 2024 · The single circular DNA represents a single chromosome. This DNA is not a supercoiled structure as in eukaryotes as they do not have histone proteins in their structure. They form loops with the help of nucleoid-associated proteins. Due to the absence of the histone scaffolding, the prokaryotic DNA is often referred to as “naked DNA”. WebSince prokaryotic cells typically have only a single, circular chromosome, they can replicate faster than eukaryotic cells. In fact, a prokaryotic cell can undergo two rounds of DNA replication before the cell, itself, has …
