Describe the rationale behind the electrophoretic mobility shift assay.
Since RNA polymerase has an error rate of 1 / 10^4 nucleotides, and the DNA polymerase has an error rate of 1 / 10^7 nucleotides, can cells tolerate errors made in transcription in comparison to errors made during DNA replication?
Why do longer DNA molecules move more slowlythan shorter ones during electrophoresis?
