How does molecular genetics add to our understanding of genes is by simply studying
them.
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.
