TrackSig: Unlocking the history of cancer through tumor evolution

A tumor is often made up of different cells, some of which have changed—or evolved—over time and gained the ability to grow faster, survive longer and potentially avoid treatment. These cells, which have an "evolutionary ...

Molecular genetics

Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level. The field studies how the genes are transferred from generation to generation. Molecular genetics employs the methods of genetics and molecular biology. It is so-called to differentiate it from other sub fields of genetics such as ecological genetics and population genetics. An important area within molecular genetics is the use of molecular information to determine the patterns of descent, and therefore the correct scientific classification of organisms: this is called molecular systematics.

Along with determining the pattern of descendants, molecular genetics helps in understanding genetic mutations that can cause certain types of diseases. Through utilizing the methods of genetics and molecular biology, molecular genetics discovers the reasons why traits are carried on and how and why some may mutate.
