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.
