The genetic material of bacteria and plasmids is DNA. Bacterial viruses (bacteriophages or phages) have DNA or RNA as genetic material. ... These latter characteristics are often selected as the inherited traits to be analyzed in studies of bacterial genetics.

Does all bacteria have DNA?

What are the basic properties of the genomes of bacteria? Most bacteria have a genome that consists of a single DNA molecule (i.e., one chromosome) that is several million base pairs in size and is "circular" (doesn't have ends like chromosomes of eukaryotic organisms).

Do bacterias have DNA or RNA?

The genetic material of bacteria and plasmids is DNA. Bacterial viruses (bacteriophages or phages) have DNA or RNA as genetic material. The two essential functions of genetic material are replication and expression.
