There are two main types of nucleic acids:
* Deoxyribonucleic acid (DNA): This is the primary molecule that carries genetic information in most living organisms. It's a double-stranded helix that contains the instructions for building and maintaining an organism.
* Ribonucleic acid (RNA): This molecule plays a crucial role in protein synthesis. It's a single-stranded molecule that copies information from DNA and carries it to the ribosomes, where proteins are built.
While RNA has its own important functions, DNA is the fundamental molecule that stores the genetic code, and RNA is involved in the process of translating that code into functional proteins.
