What is the small circular DNA found outside the genomic DNA in some bacteria called?

Options

  1. APlasmids
  2. BChromosomes
  3. CMesosomes
  4. DInclusions

Correct answer

A. Plasmids

Step-by-step solution

The genetic material is basically naked, not enveloped by a nuclear membrane. In addition to the genomic DNA (the single chromosome/circular DNA ), many bacteria have small circular DNA outside the genomic DNA. These smaller DNA are called plasmids . The plasmid DNA confers certain unique phenotypic characters to such bacteria.
