The study of the structure, function, and synthesis of DNA and RNA molecules is one of the important branches of biological studies. The study of DNA and the genes that it contains is broadly known as genomics. Gene expression has distinct roles for DNA and RNA during transcription and translation. In this book, DNA structure and function, transcription, and translation are discussed in detail. The book is ideal for college level students studying general biochemistry, biotechnology, and biology. Each chapter begins with some learning objectives, followed by innovative explanations of concepts, and lastly, references for further studies. Enjoy!
