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 Which of the following is used to determine the appropriate stringency (Wallace rule)? Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) ANSWER DOWNLOAD EXAMIANS APP
