Here's why:
* DNA carries the blueprint: DNA contains the instructions for building and maintaining an organism. It's like a codebook that tells cells how to make proteins, which are the building blocks of life.
* DNA replication: Before a cell divides, it makes a copy of its DNA, ensuring that each daughter cell receives a complete set of genetic instructions.
* Inheritance: During sexual reproduction, each parent contributes half of their DNA to their offspring. This combination of genetic material creates a unique individual with a mix of traits from both parents.
While there are other molecules involved in the process of inheritance (like RNA), DNA is the core repository of genetic information that is passed on from generation to generation.
