...faster the mice seem to learn this fear. His theory: the memory message (that darkness should be avoided) is encoded by the rats' DNA-RNA mechanism into an amino-acid chain called a peptide, a small protein that Ungar managed to isolate and then synthesize. His name for it: scotophobin, from the Greek words for "darkness" and "fear...
...chemistry involved in this transfer of fear. But after repeated experimentation, he concluded that the message was coded in amino acid chains called peptides, which are small proteins. Finally, he narrowed the search to a single peptide-consisting of a sequence of 15 amino acids-that he named scotophobin, from the Greek words for dark and fear. To check his conclusion, Ungar asked Wolfgang Parr, a University of Houston chemist, to duplicate scotophobin using only off-the-shelf chemicals. The synthetic variety differed slightly from the natural chemical produced in the brains of fear-induced rats, says Ungar...
