The paper presents data concerning the structural organization of specialized membrane structures in bacterial cells, viz. nucleoidosomes involved in DNA replication. A possible correlation between the number of homologous chromosomes in a nucleoid, the presence of nucleodosomes and their dimensions is discussed. Apparently, the role of nucleoidosomes is to increase the active surface of a plasmalemma region necessary to locate the replicative centers of circular DNA molecules in bacterial nucleoids.
