To understand the chemical basis of inheritance, we must understand the molecular structure of DNA.
earnstyle [38]

Answer:

C) reductionism

Explanation:

The approach of reductionism is applied to decipher the basic concepts that rule some complex life processes. In this approach, the complex life processes can be interpreted by explaining the physical and chemical structure of involved components and their interactions. DNA molecules store genetic information. Inheritance means the transfer of genetic traits from one generation to the next. Therefore, the chemical structure of DNA is the application of reductionism to understand the chemical basis of inheritance.
