A plasmid is an independent, circular, self-replicating DNA molecule that carries only a few genes. [1] Plasmids can be absorbed by cells, and the independant DNA inserted into the cell's genes, and thusly expressed. Plasmids often contain genes for anti-biotic resistance and are used often in biological transformation experiments as a check to see if the implanted genes worked (if the cell is resistant to a particular anti-biotic that has a resistance gene on the plasmid with the gene of interest the cells will live in the environment with the anti-biotic; eliminating any cells who did not accept the plasmid)
