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 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? It has low affinity for the correct dNTP's It lacks a proofreading exonuclease AZT (zidovudine) is too expensive to be taken in effective doses The RNase H domain of p66 causes error prone synthesis It has low affinity for the correct dNTP's It lacks a proofreading exonuclease AZT (zidovudine) is too expensive to be taken in effective doses The RNase H domain of p66 causes error prone synthesis ANSWER DOWNLOAD EXAMIANS APP
