Explanation:

it is circular DNA which have capacity to join to eukaryotic DNA.

Plasmids are the extrachromosomal, self- replicating and double stranded closed and circular DNA molecules present in the bacterial cell. Plasmids contain sufficient genetic informations for their own replication. Plasmids are used as vectors because they can carry a foreign DNA fragment when inserted into it.
