Small rings of DNA are called what?

Explanation:
Small rings of DNA are called plasmids. Plasmids are circular DNA molecules that exist apart from the bacterial chromosome and replicate independently. They usually carry extra genes that can give advantages to the cell, such as antibiotic resistance or new metabolic capabilities. In the lab, plasmids are prized as vectors for introducing new genes into cells. By contrast, the bacterial chromosome is the larger circular DNA molecule that holds essential genes, the genome is the organism’s complete set of genetic material, and the nucleoid is the region inside the cell where the chromosome is located.
