DNA polymerase can only add nucleotides to a free 3(-hydroxyl group on a nucleic acid strand. As a consequence, all EXCEPT which of the following statements are true of DNA replication?

A) Synthesis of one complementary DNA strand lags behind the synthesis of the other strand.
B) DNA replication requires both DNA polymerase III and DNA polymerase I.
C) Primase must synthesize an RNA primer before DNA synthesis can begin.
D) Uracil is not found in DNA.

Hey! The answer to your question would be, A. Synthesis of one complementary DNA strand lags behind the synthesis of the other strand. Hope this helps. :-)

answer; i believe the answer is hydraulic action;

"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."
