The sequence below corresponds to the first 15 bases of the open reading frame of the E. coli cysS gene. For each of the following mutation sequences, determine the amino acid sequence encoded by the 15 bases, identify whether the mutation is a transition, transversion, insertion, deletion. Also identify whether the mutation is a missense, nonsense, silent or frame-shift mutation. 5' ATG CTA AAA ATC TTC a. 5' ATG CTA AAG ATC TTC b. 5' ATG CTA TAA ATC TTC c. 5' ATG CTA AAA AAT CTT d. 5' ATG CGA AAA ATC TTC

"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."
