D. plasmid
Explicación
## Step 1The problem is asking us to identify a small ring of DNA found in a bacterial cell. The options provided are gene, bullet, virus, PCR, and plasmid.## Step 2We need to understand what each of these terms means in the context of biology. - A gene is a segment of DNA that contains the instructions for making a specific protein.- A bullet is a projectile, not a biological term.- A virus is a small infectious agent that replicates only inside the living cells of an organism.- PCR (Polymerase Chain Reaction) is a method used in molecular biology to make many copies of a specific DNA segment.- A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA and can replicate independently.## Step 3Given the definitions, the term that best fits the description of a small ring of DNA found in a bacterial cell is a plasmid. Plasmids are small, circular, double-stranded DNA molecules that are distinct from a cell's chromosomal DNA and can replicate independently.
