Osmosis video - DNA cloning

DNA cloning is the process of making multiple copies of a piece of DNA, like a gene. This can be done in many ways, including inserting a target gene into a circular piece of DNA called a plasmid. The plasmid is then transferred into the bacteria in a process known as transformation, and bacteria carrying the plasmid are then selectively grown, making multiple copies of the chosen gene or even synthesizing its encoded protein.
