Sorry, no etymologies found.
In the first experiment, as illustrated in Figure 13-2, we extracted from each brain paired DNA strands, used the restriction enzyme TAQ1 to cut them into smaller fragments (ABC), and placed the fragments in solution in small test tubes (ABC).
I called him that same day, and he agreed to send me the probe, suggesting that we try the restriction enzyme TAQ1 that he had used in his experiments on humans.
