bacteria plasmids are useful in biotechnology
Importance. Plasmids come in many different sizes and are used for many different purposes in biotechnology. They first made their mark in the field of recombinant DNA in the 1970s, being used as a tool to insert genes into bacteria to encourage their production of therapeutic proteins such as human insulin.ble to self-replicate, plasmids can be picked up from the environment and transferred between bacteria. Plasmids are used by their host organism to cope with stress-related conditions. Many plasmids, for example, carry genes that code for the production of enzymes to inactivate antibiotics or poisons.
