No. Many viruses exist as vehicles for the replication of RNA rather than DNA. All known organisms have either RNA or DNA.
However, this does not mean that some other molecule could not hypothetically have the same role in organisms as modern-day RNA/DNA does in modern organisms. In fact, many hypotheses within the field of abiogenesis research have cellular life emerging from molecular replicators that were not RNA or DNA.
What else can I help you with?
Is the DNA in the heart the same DNA in the brain?
Every single cell in the human body contains identical genetic information. Every cell contains all of the information required to create a copy of yourself.
What key ingredient is required in every step in the process of translating from DNA to mrna to trna into a polypeptide chain?
Translation
How often is DNA?
DNA is copied every time a cell divides. Different types of cells divide at different rates.
Time required for DNA replication in E. coli?
E.coli will take 15 to 20 minutes to undergo the entire cell division cycle exact time for DNA replication is not known.
Where is the ozone layer harmful?
Nowhere is it harmful. It is required everywhere the Sun shines for the protection of DNA-based life.
How often is DNA copyed?
DNA is copied every time a cell divides. Different types of cells divide at different rates.
What substance contains the instructions for life?
DNA (deoxyribonucleic acid) contains the instructions for life. DNA is a molecule that carries the genetic instructions necessary for the growth, development, functioning, and reproduction of all living organisms.
Where is DNA found in the cell and what is its code for?
DNA is found inside the nucleus in every cell and contains all of the information required to create your body as well as perform any/all function(s).
What is the chemical that provides detailed instructions to the cell about every function of life?
This chemical is DNA - deoxoribonucleic acid.
How DNA decides individuality of an organism?
Every life form have different genetic pattern. Then again there are minor variations in every individual to make him special from that species. This is true for all the organisms, except perhaps the single celled organisms. There are many more than required permutations and combinations to permit the individuality.
What cells do not have DNA?
every cell has dna
Why DNA is blue print of life?
DNA is the blueprint to every living thing on our planet. The DNA determines what you look like, if you are a tiger or an oak tree. DNA determines eye and hair color, gender, and just about everything else about you.
