Here's why:

* DNA to RNA to Protein: Genes are segments of DNA that hold the code for building proteins. The process of protein synthesis involves two main steps:

* Transcription: The DNA sequence of a gene is copied into a messenger RNA (mRNA) molecule.

* Translation: The mRNA molecule travels to ribosomes, where it's used as a template to assemble amino acids into a protein.

* Proteins are the Workhorses of the Cell: Proteins are essential for virtually every function in a living organism. They act as:

* Enzymes: Catalyzing biochemical reactions.

* Structural components: Providing support and shape to cells and tissues.

* Hormones: Regulating bodily functions.

* Antibodies: Defending against infections.

So, the information encoded in genes is the blueprint for building proteins, which in turn drive all the processes that make life possible.
