Here's why:
* DNA contains the blueprint: DNA holds the instructions for building and maintaining an organism. These instructions are encoded in the sequence of its four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
* DNA replication: When a cell divides, its DNA is copied (replicated) so that each new cell receives a complete set of instructions.
* Protein synthesis: DNA provides the code for creating proteins, which are the building blocks and workers of the cell. This process is called protein synthesis and involves RNA (Ribonucleic acid) as an intermediary.
While RNA also plays a crucial role in carrying genetic information and protein synthesis, it is DNA that holds the primary, long-term blueprint for life.
