DNA Structure and Replication In a typical electrophoresis experiment, larger fragments of DNA move more slowly, so they appear nearer the top of a gel photograph quickly, so they appear nearer the bottom of a gel photograph slowly, so they appear nearer the bottom of a gel photograph quickly, so they appear nearer the top of a gel photograph slowly, so they appear nearer the top of a gel photograph quickly, so they appear nearer the bottom of a gel photograph slowly, so they appear nearer the bottom of a gel photograph quickly, so they appear nearer the top of a gel photograph ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication The size of a linear DNA fragment in a gel can be estimated by the sedimentation coefficient the time it takes the gel to run comparison with a molecular weight standard such as Hind III digested phage lambda fluorescence in UV light the sedimentation coefficient the time it takes the gel to run comparison with a molecular weight standard such as Hind III digested phage lambda fluorescence in UV light ANSWER DOWNLOAD EXAMIANS APP

DNA Structure and Replication Which of the following is used to determine the appropriate stringency (Wallace rule)? 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 G:C base pair) + 2 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 = 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 G:C base pair) + 2 x (No.of A:T base pair) Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) ANSWER DOWNLOAD EXAMIANS APP
