"Recombinant DNA Techniques: A Textbook" has all the techniques used in the Genetic Engineering like the PCR, Microarray, transfection techniques, Blotting techniques, DNA sequencing, site directed Mutagenesis and protein engineering. It also includes various aspects of the gene therapy. It also have the good description of the mapping techniques along with the various molecular markers used in the mapping of the genomes like RFLP, RAPD, AFLP etc. DNA chip technology is the most important techniques used for the study of the gene expression and it is the only technique that can analyze the multiple genes at a time. This techniques is very well explained in the book. DNA sequencing by Sanger's Method and maxam and Gilbert's method is also explained by the help of good diagrams. These are the important topics covered in this book.
