Understanding:
• Molecular biology explains living processes in terms of the chemical substances involved
Molecular biology is a field of study that focuses on investigating biological activity at a molecular level
- This includes elucidating the structure and function of chemical substances and determining their interactions as parts of living processes
Biological processes are tightly regulated by enzymes, whose expression is controlled by gene activation (DNA)
- Changes in activity are typically determined by signalling molecules (either endogenous or exogenous in origin)
