Answer:
by combining the DNA of two different organisms
Step-by-step explanation:
Recombinant DNA is when researchers edit a gene to contain a novel sequence, such as one from another organism
A good example of this in the lab is when scientists combine genes with a fluorescent gene called green fluorescent protein, GFP. This is from jellyfish. The gene sequence can be tracked on to the end of a gene of interest in a cell population or organism. When the gene is transcribed and translated, the GFP sequence will also be transcribed and translated. This means it will be fluorescent green and easy to track and visualise in cells.
