The biological field which deals with the study of inheritance in human beings is called human genetics. Human molecular genetics is one of its sub-fields where the functions and structure of human genes are studied at the molecular level. It uses tools from numerous fields such as genetics and molecular biology. Human molecular genetics finds application in the study of developmental biology as well as in the treatment of genetic diseases. There are a number of techniques which are used within this field such as forward genetics, reverse genetics and DNA replication. This book attempts to understand the multiple branches that fall under the discipline of human molecular genetics and how such concepts have practical applications. The topics covered herein deal with the core subjects of this field. This textbook will provide comprehensive knowledge to the readers.
