Protocol that uses the polymerase chain reaction (PCR) to quantitate the numbers of a particular DNA sequence, from 1 to 20,000 molecules per sample. In addition, it helps assess the presence of contaminating sequences, which can seriously affect the outcome of the procedure. - [Read Quantitation of Rare DNAs by PCR Protocol]
The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
