Solution:

: Plasmid is a small, extrachromosomal, circular molecule of DNA that replicates independently of the host DNA. They are found in bacteria. They are divided into two classes: the large plasmids which include certain bacteriocinogens and the small plasmids which include those from 1.5 to . in length. They are used as vectors in genetic engineering.
