Solution
The correct option is D Single-stranded A plasmid is a small, circular, double-stranded extrachromosomal DNA. It is found in bacterial cells, and in some eukaryotes also. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. A plasmid is an independent, circular, self-replicating dsDNA molecule that carries only a few genes.
