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.
Yes, ribose is present in the RNA of living organisms, but not in the DNA.
Some organisms use uracil instead of thymine in their DNA/RNA because uracil is more easily produced and can be converted from a common molecule, making it a more efficient choice for these organisms.
Yes, both single-stranded DNA and RNA are found in living organisms.
Yes. DNA is the fundamental blueprint for all life on Earth.That depends on your definition of Life.Are viruses alive? Some say yes and some say no. Some viruses have DNA, and some only have RNA. So if you consider viruses a form of life, then some do not have DNA. RNA virus examples are SARS and Hepatitis. If you don't consider viruses alive, then yes, all forms of life (that we know of) higher than a virus contains some form of DNA. You can find out more at the link below.
Yes, the genetic material in living organisms can be double stranded, as seen in DNA, or single stranded, as seen in RNA.
Yes, ribose is present in the RNA of living organisms, but not in the DNA.
yes, but many viruses do not have DNA genome, but RNA genome.

Yes every organisms have them. Some virus have RNA
No, for example some organisms also have RNA among them.
RNA is typically single-stranded, while DNA is double-stranded. RNA carries genetic information in some viruses and acts as a messenger between DNA and ribosomes during protein synthesis. DNA stores genetic information in most organisms and is the blueprint for the development, growth, and functioning of living organisms.
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.
DNA are replicator molecules. DNA molecules are able to male copies of themselves in a process called DNA replication. RNA molecules however, are synthesized using a DNA template through a process called transcription
In cells they are in DNA. In virus they are in DNA or RNA
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.
