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%? Remains same Can not be compared Increases Decreases Remains same Can not be compared Increases Decreases ANSWER DOWNLOAD EXAMIANS APP
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?
