Sweet Biochemistry: Remembering Structures, Cycles, and Pathways by Mnemonics, Second Edition makes biochemistry lively, interesting and memorable by connecting objects, images and stories to biochemistry concepts. Here, Dr. Asha Kumari has converted cycles and difficult pathways into very simple formula and short stories and images to help readers see things in complicated cycles and better visualize biochemistry. As biochemistry is evolving steadily, with new and impactful topics, this new edition has been fully updated to include mnemonics on timely topics in biochemistry such as DNA replication, RNA, transcription, translation, and CRISPR technology, as well as fundamentals of immunity.
