Here's why:
* DNA contains genetic information: DNA is a long, complex molecule that carries the instructions for building and maintaining an organism. These instructions are encoded in the sequence of its building blocks, called nucleotides.
* DNA replication: During cell division, DNA is copied exactly, ensuring that each new cell receives a complete set of genetic instructions.
* Inheritance: DNA is passed from parents to offspring through reproductive cells (sperm and egg). This means that the offspring inherit traits and characteristics from their parents.
While RNA also plays a crucial role in gene expression, it doesn't directly pass genes across generations. RNA is a copy of a specific gene's DNA sequence, used to build proteins. It is not typically passed on to offspring.
