Molecular Biology and Genetics seek to understand how the molecules that make up cells determine the behavior of living things.
Biologists use molecular and genetic tools to study the function of those molecules in the complex milieu of the living cell.
Genetics deals with genes, genetic variation, gene mutation, and heredity; with a heavy focus on “trait inheritance'.
The science of genetics is important because many of the diseases have their roots in gene mutations or polymorphisms.
Molecular biology allows the study of gene functions, mutations, and polymorphisms.
