If cells were fed glucose with radioactive 14c, what other molecule besides co2 would you expect to be radiolabeled? see section 9.1

The answer is; All biological molecules like nucleotides, fats, and amino acids

This is because intermediate of the biological pathways such as the pyruvate and Krebs system is also used in the synthesis of other biological molecules such as fats , nucleotides and amino acids. An example is the acetyl-CoA intermediate product of the Krebs cycle is used to synthesize fats in the fatty acid synthesis process.  This shows that the carbon-14 is transferred to these different biochemical process hence will be found various biomolecules.

"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."
