  • in a common sense, yes. A virus however is not classified, as biotic, nor abiotic, yet has DNA :)
  • All living organisms have DNA.
  • rna viruses....which are very much alive.....cause they not only metabolize but reproduce inside a host.....have rna as their genetic material and not dna. So, rna and dna, both can exist as the genetic material, and hence the statement that all living forms have dna is not entirely true. Peace.
  • No. There are viruses that are considered "alive" that do not contain DNA. These are referred to as RNA viruses.
