It would be easier to ask what organisms do not have DNA, as all living organisms contain genetic material within them. The answer would be those viruses that only employ RNA as a replication agent such as the Tobacco Mosaic Virus.

Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
What holds an organisms hereditary information.?
In cells they are in DNA. In virus they are in DNA or RNA
Are DNA or RNA made up of genes?
Amost all organisms have genes that are made of DNA (deoxyribonucleic acid) but there are some kinds of viruses known as retroviruses whose genes are composed of RNA (ribonucleic acid).
Why Are Nucleic Acids Important To Living Things?
Nuleic acids (DNA, RNA) are important information carrying molecules in all living organisms. DNA is generally used to carry the genetic information of living organisms and RNA is genereally involved in the transcription (mRNA) and translation (tRNA) processes that result in the production of proteins from genes coded by DNA.
This holds an organisms hereditary information?
In cells they are in DNA. In virus they are in DNA or RNA
What controls the heredity of organisms?
DNA in most organisms (although some have RNA instaid.)
What is the correct sequence of the transfer of information in most organisms?
Dna to Rna to Proteins
Do all organism on earth have DNA?
No, for example some organisms also have RNA among them.
Do all iving consist of DNA?
Yes every organisms have them. Some virus have RNA
Is DNA required every time in life?
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.
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
Holds an organisms hereditary information?
In cells they are in DNA. In virus they are in DNA or RNA
What holds an organisms hereditary information.?
In cells they are in DNA. In virus they are in DNA or RNA
Did RNA exist before DNA?
There are many reasons why scientists think RNA came before DNA. RNA is found in viruses and some bacteria which were likely around before more complex organisms.
Are DNA or RNA made up of genes?
Amost all organisms have genes that are made of DNA (deoxyribonucleic acid) but there are some kinds of viruses known as retroviruses whose genes are composed of RNA (ribonucleic acid).
How do biologists use DNA and RNA to help classify organisms?
DNA and RNA shows how similar or different the organisms are, so you can group them into categories based on how similar they are to one another.
What do all organisms do in common?
All organisms use DNA and rna to pass on information.
