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 The RNase H domain of p66 causes error prone synthesis It lacks a proofreading exonuclease It has low affinity for the correct dNTP's AZT (zidovudine) is too expensive to be taken in effective doses The RNase H domain of p66 causes error prone synthesis It lacks a proofreading exonuclease It has low affinity for the correct dNTP's ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication In the study of one experiment it was found that the value of Tm for DNA is = 40° C. If the cell has 20% GC at the above Tm, then what will be value of 'Tm' if the GC% increases to 60%?

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? All of these The many different amino acid R groups on proteins confer many different shapes. Some S amino acids cause proteins to bend; others cause protein to flatten. DNA has one main function in cells whereas proteins have many. All of these The many different amino acid R groups on proteins confer many different shapes.
