Bacterial DNA is referred to as naked because it is not associated with proteins (specifically histone proteins).

The term “naked DNA” in the context of bacteria refers to the fact that their DNA is not complexed with histone proteins to form chromatin, as is the case with eukaryotic DNA. While bacterial DNA does associate with some non-histone proteins for packaging and organization, the absence of histones is the defining characteristic leading to the term “naked”.

Eukaryotic DNA is wrapped around histone proteins to form nucleosomes, which are further folded to form chromatin. This structured packaging is absent in prokaryotes. Plasmids are extra-chromosomal DNA found in bacteria, not proteins associated with the main chromosome.
