If by non-living you mean an object such as a sheet of metal then no they are not composed of cells. If you are referring to something dead, then yes the DNA is still intact at least for a while anyway they do deteriorate in time.
No, living thing shave DNA and genes which kind of affects its appearance (like humans and plants). Nonliving things do not have genes and DNA.
An organism is not "nonliving." Many biologists consider viruses to be non-living. Many viruses contain DNA.
This is just one of those things that are what they are. Rocks don't have DNA. Living things need DNA as the genes are carried there and the genes make a thing a horse, a person or a cat.
The general term for organisms that contain foreign DNA that has been artificially inserted is transgenic
Prions are an infectious particle made of protein. They do not contain DNA or RNA.
Yes, as organisms, eukaryotes contain DNA.
because the organisms eat the dead / nonliving environment
Chromosomes contain links of amino acids and other chemicals. They determine everything about organisms, Chromosomes contain DNA, which is the blue print of any organism
Contain DNA
The general term for organisms that contain foreign DNA that has been artificially inserted is transgenic
Chromosomes contain organisms' DNA. DNA is the genetic information that controls the traits of organisms. Chromosomes are found on DNA.
Prions are an infectious particle made of protein. They do not contain DNA or RNA.
contain DNA
Yes, as organisms, eukaryotes contain DNA.
because the organisms eat the dead / nonliving environment
Recombinant DNA is made of DNA taken from two different organisms. It may contain plant DNA but this is not always the case.
the earth is nonliving but has living organisms on it
because the organisms eat the dead / nonliving environment
All organisms are living.
Your question is an oxymoron. Nonliving means they are dead. If it is dead it ceases to be an organism. Organisms are alive.
