Yes, they do use real DNA.

Scientists use ancestors and DNA to group species.
Scientists use Ancestors and DNA to group DNA.
Scientists use an enzyme called restriction enzyme to cut genes out of strands of DNA.
One reason why scientists may use bacterial DNA over human DNA in biotechnology is because bacterial DNA is often easier and cheaper to manipulate and study given its simpler structure compared to human DNA.
houg
Scientists use DNA ligase to bond a new gene to plasmid DNA. DNA ligase catalyzes the formation of phosphodiester bonds between the ends of the new gene and the plasmid, creating a recombinant DNA molecule.
It is true that Scientists use gel electrophoresis to cut DNA molecules at a specific sequence of nucleotides.
DNA is the answer.
