modification of the structural and functional properties of cloned DNA sequences. Techniques have been refined to the point where virtually any desired change or series of changes in the nucleotide sequence may be rapidly introduced. Several methods also exist for the introduction of random rather than targeted mutations, thus allowing the identification of structurally or functionally important regions that might not otherwise be detected. This book draws together a wide range of methods for the efficient directed mutagenesis of cloned DNA sequences. It provides up-to-date protocols and practical advice that will prove valuable to the beginner who wishes to be guided through the available approaches, and to the experienced researcher interested in exploring alternative procedures.
