After the genetically modified plasmids are inserted into bacteria; the bacteria make proteins from the inserted modified genes.

Explanations;
Plasmids are small, circular strands of DNA that are present in bacterial cells and are capable of self-replication. To add pieces of foreign DNA to bacteria, scientists first package the DNA of interest within the plasmid, and then induce the bacteria to take up the vector. This in turn makes the host bacterium a new, genetically modified organism. Once inside the bacteria, foreign proteins can be made within the bacteria, that is; if the introduced DNA is a gene that encodes a protein, then gene's protein product can be studied by expressing it in the bacteria.
