Plasmids naturally exist in bacterial cells ... for these purposes are called vectors. Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant ...

Within the lab environment, bacteria are also commonly transformed with sequences of DNA called plasmid vectors. These naturally occurring DNA molecules are circular, and they can replicate inside ...

A new study has uncovered how the defense mechanisms of bacteria can be neutralized, facilitating more efficient genetic ...
