Scientists seeking to determine which molecule is responsible for the transmission of characteristics from one generation to the next knew that the molecules must (1) copy itself precisely (2) be stable but able to be changed and (3) be complex enough to determine the organism’s phenotype. a. explain how dna meets each of the three criteria stated above. b. select one of the criteria stated above and describe experimental evidence used to determine that dna is the hereditary material.

i think the answer would d

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
