DNA Structure and Replication The higher order structure of DNA shows symmetry, whereas the higher order structures of most proteins do not. Why isn't protein shape more regular like DNA? The many different amino acid R groups on proteins confer many different shapes. All of these DNA has one main function in cells whereas proteins have many. Some S amino acids cause proteins to bend; others cause protein to flatten. The many different amino acid R groups on proteins confer many different shapes.

DNA Structure and Replication The rapid appearance of HIV-1 strains that are resistant to AIDS drugs is due in part to which of the following property of its reverse transcriptase? AZT (zidovudine) is too expensive to be taken in effective doses It lacks a proofreading exonuclease It has low affinity for the correct dNTP's The RNase H domain of p66 causes error prone synthesis AZT (zidovudine) is too expensive to be taken in effective doses It lacks a proofreading exonuclease It has low affinity for the correct dNTP's The RNase H domain of p66 causes error prone synthesis ANSWER DOWNLOAD EXAMIANS APP
