Answer:
C. A small, circular piece of DNA
Explanation:
A plasmid, usually circular but sometimes linear, is a small double-stranded DNA unit, which is chromosome independent and is capable of self-replication. Each plasmid carries only a few genes. Carrying only a few genes, the plasmid’s size ranges from 1 to more than 1000 kbp. Genes required for organism survival and those that are generally beneficial to the host organism, such as antibiotic resistance, are often found in plasmids [1].
Mostly plasmids can be found in bacteria, but they are also present in multicellular organisms and archaea. Plasmids usually contain at least one gene and are not considered independent life forms even though they possess separate genes from their hosts
