I am new here, and I am writing a paper for extra credit. I basically know how, I just cannot find any good examples or sources, and I am still a little confused on the whole DNA chapter.
Well the most obvious example is in the field of genetic diseases
search for human perspectives accounted in the study.
not exactly discoveries in DNA, but you might wanna look up RNA interference(Nobel prize in medicine and physiology in 2005, if i remember correctly)
