Cloning and identifying genetically caused diseases
Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.
Molecules of most elements are made up of only one of an atom of that element.Oxygen,nitrogen hydrogen and chlorine are made of two atoms
