Answer:
The scientist can insert the DNA into bacteria
Explanation:
Bacteria are frequently used in biotechnology to make proteins scientists are interested in. If they know the gene and the sequence of the gene that makes the protein product, they can insert that gene into a vector that will cause the bacterial transcription and translation machinery to produce the protein.
Firsts scientists clone their DNA of interest into a vector, a circular piece of DNA that the bacteria will transcribe. The vector is then introduced to competent bacterial cells. (Competent means there are holes in the bacterial membrane that allow them to uptake the gene and vector).
Once the vector is in the bacteria, it (and the gene of interest) will be transcribed and translated as it would in the chicken liver.
