Here's why:
* DNA contains the genetic code: DNA is a long, complex molecule that holds the instructions for building and maintaining an organism. These instructions are encoded in the sequence of its four nucleotide bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
* DNA replication: During cell division, DNA replicates itself, ensuring that each new cell receives a complete copy of the genetic information.
* Inheritance: When organisms reproduce, they pass on copies of their DNA to their offspring. This is how traits are inherited from parents to children.
While ribonucleic acid (RNA) is also a nucleic acid, it plays a different role in protein synthesis and doesn't directly carry genetic information across generations.
