More Information
Escherichia coli is a type of prokaryotic cell, and like all prokaryotes, it does not have a membrane-bound nucleus. Instead, it has a region called the nucleoid where its DNA is located.
Tips
A common mistake is to confuse the nucleoid with a true nucleus. Unlike a eukaryotic nucleus, the nucleoid is not membrane-bound.
