Biomedical engineers design artificial body parts, medical devices, diagnostic tools, and medical treatment methods. 0338326. Note that the GAAT sequence is repeated twice in the father's side and three times in the mother's side (the sides of each chromosome are often not the same length). It was only three days into 1956 when three boys from Montana, out for a hike on a normal January day, made a gruesome discovery they were unlikely to ever forget.
