Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

New Insights Reveal Bacterial Roots of Key Plant Hormone Enzymes

Terpenoids play vital roles in plant ecology-from repelling pests to attracting pollinators-and are produced by terpene synthases (TPSs) enzymes.
