When the first edition of GENES published, Benjamin Lewin set the standard for teaching molecular biology and molecular genetics with a unified approach. The Ninth Edition of this classic text continues this tradition, presenting gene structure and function in both eukaryotic and prokaryotic organisms. Dr. Lewin maintains his commitment to providing students, researchers, and educators with the most current presentation of concepts in this rapidly changing field. The Ninth Edition of GENES includes updated content and expanded coverage of critical topics with a new organization that allows the student to focus more sharply on genes and their expression. GENES IX also boasts a fresh, modern design and a contempoary art program. Inglés
