A Bacterial Genome is Typically

Question

A bacterial genome is typically
A) a single linear piece of DNA.
B) multiple linear pieces of DNA.
C) a linear RNA molecule.
D) a single circular DNA molecule.
E) multiple circular DNA molecules.

Accepted Answer

A bacterial genome is typically represented as a single circular DNA molecule. This is unlike the genomes of eukaryotes, which consist of multiple linear chromosomes. Some bacteria may have plasmids, which are smaller circular DNA molecules, but the main chromosome is typically a single circular DNA molecule.
