Here's why:
* DNA holds the genetic code: DNA contains the instructions for building and maintaining an organism. This information is encoded in the sequence of its four nucleotide bases (adenine, guanine, cytosine, and thymine).
* Genes are segments of DNA: Each gene within DNA provides the code for a specific protein.
* Transcription: The information from DNA is first transcribed into messenger RNA (mRNA).
* Translation: mRNA then travels to ribosomes, where it is translated into a chain of amino acids, ultimately forming a protein.
So, DNA is the blueprint for protein synthesis, providing the essential information for creating the diverse array of proteins that carry out all the functions of a cell and organism.
