The pattern and extent of DNA methylation can significantly affect the success of restriction digestions
or bacterial transformations. Prokaryotic DNA may be methylated by host restriction/modification
systems, while eukaryotic DNA often is methylated i - [Read A practical guide to DNA methylation Promega PDF]
In this protocol sequences cloned in standard bacteriophage or plasmid vectors are amplified in PCRs containing primers targeted to flanking vector sequences. The amplified fragments can be analyzed by gel electrophoresis, DNA sequencing, and/or restriction mapping. Many colonies or plaques can be assayed simultaneously. - [Read Rapid Characterization of DNAs Cloned in Prokaryotic Vectors Protocol]
