By inserting the genes of a plant that produces an enzyme or other protein that can be used as medicine into a bacteria cell's DNA, scientists can produce genetically engineered bacteria that act as factories to produce that
enzyme or protein in greater amounts.

Explanation:

In a typical cloning experiment, a target gene is inserted into a circular piece of DNA called a plasmid. The plasmid is introduced into bacteria via a process called transformation, and bacteria carrying the plasmid are selected using antibiotics.
