Are all RNA viruses single stranded?

An RNA virus is a virus that has RNA (ribonucleic acid) as its genetic material. This nucleic acid is usually single-stranded RNA (ssRNA) but may be double-stranded RNA (dsRNA).

Considering this, can viruses have single stranded DNA?

A DNA virus is a virus that has DNA as its genetic material and replicates using a DNA-dependent DNA polymerase. The nucleic acid is usually double-stranded DNA (dsDNA) but may also be single-stranded DNA (ssDNA). Single-stranded DNA is usually expanded to double-stranded in infected cells.

One may also ask, do all viruses have RNA?

Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.

Is there DNA in viruses?

A virus is a small parasite that cannot reproduce by itself. Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein.

Why can't viruses be killed?

Viruses live and replicate inside of a human cell, they cannot live outside of this environment. Viruses insert their genetic material into a human cell's DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate.
