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 Decreases Increases Remains same Can not be compared Decreases Increases ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication What does ligase do during replication of DNA? Digests mRNA when it is no longer needed Makes copies of mRNA from DNA Joins nicks in DNA strands Synthesizes the lagging strand Digests mRNA when it is no longer needed Makes copies of mRNA from DNA Joins nicks in DNA strands Synthesizes the lagging strand 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 = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 4 x (No.of G:C base pair) + 2 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 = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) ANSWER DOWNLOAD EXAMIANS APP
