DNA: ** Deoxyribonucleic acid - **A self-replicating material present in nearly all living organisms as the main constituent of chromosomes.

Well, because of the answer, this question, can life exist without DNA is not valid. Most living things contains DNA. DNA is crucial in order to live, without it we would not exist! DNA is as important as food, water and breathing. Life is not possible without DNA. Earlier in the response is stated that most living things need DNA to survive. This leaves us with a few organisms and viruses that don't need it to survive. I thought about this and I had a question. If certain organisms don't need DNA to live they must need something else to keep them alive. To some viruses, RNA is like DNA to us humans, it essential to live. RNA stands for Ribonucleic acid. It is a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA.

**Organism:** An individual animal, pant or single-celled life form. **Virus:** an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seem by light microscopy, and is abel to multiply within the living cells of a host
