Chemistry has played a vital role in making routine, affordable sequencing of human genomes a reality. Nucleic acid therapeutics is a field that has been continually innovating to meet. With extensive coverage of synthesis techniques and applications, this book describes chemical biology techniques which have extended significant stimulus during the last five years. Nucleic acid base sequence of proteins plays a crucial role in the expression of gene. The gene is responsible for the synthesis of proteins and these proteins, which are synthesized, are responsible for the biological process and also for dreadful diseases as well.
