Plasmid is a boon to biotechnology. Justify.

• Plasmids and restriction enzymes are the two tools developed the Genetic engineering and biotechnology  for the manipulation of DNA. 
• Plasmids are small, circular or linear DNA which have the capability of replicating on their own. 
• Plasmids served as a boon for biotechnology as they served as ideal vectors for transfer of DNA from one organism to another. 

The following properties make them important:

• Easy to manipulate
• Express the genes inserted into them
• Replicate own there own and can multiply to form large numbers
• Easily enter the host organism
• Small in size; so can be easily studied and modified
• Easy to handle
