Genetics & Molecular Biology is a science that teases apart the molecules that form the basis of life, to understand how we inherit physical traits and why we are susceptible to particular conditions, diseases, or disorders. Genetics is a branch of biology that is concerned with how heritable traits are transmitted from generation to generation. The study of genes and gene variations plays a central role in genetics. Molecular biology is a branch of biology that takes a “bottom up” approach to understand life. This involves examining the nucleic acids and proteins that are synthesized using the genetic instructions. Genetics and molecular biology are intricately linked, with molecular biology providing the tools and technologies to answer genetic questions, and to modulate how cells function.
