Do viruses have DNA Yes or no?

Question

Viruses are microscopic parasites responsible for a host of familiar – and often fatal – diseases, including the flu, Ebola, measles and HIV. They are made up of DNA or RNA encapsulated in a protein shell and can only survive and replicate inside a living host, which could be any organism on earth.

Does a virus have DNA?

Unlike cells (e.g. bacteria, plant and animal cells), viruses contain either DNA or RNA, never both; the viral nucleic acid is either single or double stranded. Viruses with a DNA core are capable of surviving in the nucleus of the cell they infect, using the host's biochemical machinery to replicate their DNA.

Why do viruses do not have DNA?

All living things have DNA, but technically speaking, viruses aren't living things because they can't maintain themselves or reproduce on their own. They also aren't technically cells because virus structure doesn't have organelles -- cellular machinery -- of their own.

Do viruses contain only DNA or RNA?

Viruses are smaller and simpler in construction than unicellular microorganisms, and they contain only one type of nucleic acid—either DNA or RNA—never both.

Do viruses have DNA or RNA but not both?

All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.
