DNA Structure and Replication What does ligase do during replication of DNA? Joins nicks in DNA strands Makes copies of mRNA from DNA Synthesizes the lagging strand Digests mRNA when it is no longer needed Joins nicks in DNA strands Makes copies of mRNA from DNA Synthesizes the lagging strand Digests mRNA when it is no longer needed 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 = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) 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 = 69.3° + 0.41 (%)G+C -650/1 Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) 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) ANSWER DOWNLOAD EXAMIANS APP
