#2
Bacterial genetic material is not associated with proteins, and consists of a DNA loop with a single copy of each gene.

#3
Bacterial genetic material is associated with proteins and consists of a DNA loop with multiple copies of each gene.

#4
Bacterial genetic material is not associated with proteins, and consists of several small DNA molecules with multiple copies of each gene.
