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 slowly, so they appear nearer the bottom of a gel photograph quickly, 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 slowly, so they appear nearer the bottom of a gel photograph quickly, 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 time it takes the gel to run fluorescence in UV light the sedimentation coefficient comparison with a molecular weight standard such as Hind III digested phage lambda the time it takes the gel to run fluorescence in UV light the sedimentation coefficient comparison with a molecular weight standard such as Hind III digested phage lambda ANSWER DOWNLOAD EXAMIANS APP
