The discovery of DNA is listed as a choice for Top British Innovation. First, can the terms "discovery" and "innovation" can be used interchangeably? Second, I don't know that the DNA discovery can be classified strictly as British. Despite location and the fact that 3 of the 4 main people involved were British, I think it would be difficult to give one nationality claim to the discovery. In addition to the most obvious issue of Watson being American, it also ignores the data contributions of other scientists (e.g. Chargaff). One of the reasons the whole DNA discovery story is great for a science class is that it gives great examples of collaboration, competition, and combining data from various sources to reach new conclusions.
