All viruses have genes made from either DNA or RNA but they themselves don't have DNA.
(Viruses use tRNA or mRNA or DNA as a tool for infecting host cells, but they they do not use either for their own internal bio-mechanics)
Viruses have their own genome which can be made of RNA or DNA, so some do contain DNA.
Some viruses, but not all. All viruses have some sort of nucleic acid, whether single-stranded DNA, double-stranded DNA, single-stranded RNA, or double-stranded RNA.
the virus ( in simple words) consists of:genetic material surroundedby protein capsid this genetic material can be one of the following : 1- single stranded DNA 2- double stranded DNA 3- single stranded RNA 4- double stranded RNA so some viruses contain DNA but not all. written by : asma aburas ; medical student .
Yes,viruses contain either DNA or RNA depending on the type of the species.There are certain viruses which have single stranded DNA/RNA and even double stranded DNA.Well,DNA is a genetic material like wise RNA is also a genetic material..eg.Rubella is caused by a RNA-containing virus whereas smallpox is caused by a DNA -containing virus.
Some viruses do have DNA, which is enclosed within the protein shell. However, it's not always DNA that is contained within. It can also be ssRNA, dsRNA, or even ssDNA.
yes, But not compulsory there are so many RNA viruses also present
Viruses are made of a protein shell and either DNA or RNA. Viruses with RNA are called "retroviruses."
No they don't
the cel l nucleus contains genetic material known asDNA
The genetic material that viruses have is RNA. Viruses are unable to truly carry out the processes associated with holding their own DNA.
The special molecule that contains genetic material is called a chromosome.
it can be DNA or RNA
Viruses are not considered alive because they cannot reproduce on their own. They must invade another cell or bacteria and implant their genetic material into that organism's genome in order to replicate.
Viruses contain an inner nucleic acid core (genetic material) and an outer protein coat (capsid).

genetic material of their own
Tests have shown that it contains genetic material from Human, Avian, and Swine influenza viruses.
The special molecule that contains genetic material is called a chromosome.
Because bacteria have only DNA as genetic material but viruses have RNA or DNA as genetic material. viruses are harmful but most of the bacteria are useful.
The hereditary material of viruses vary. Some viruses have DNA and some RNA. Viruses with RNA change, for example the flu, that's why we get a shot every year. The viruses with DNA don't change so that's why you need only one shot.
1. A virus attaches to a bacterium. 2. The virus injects its genetic material. 3. The genetic material of the virus combines with the bacterium's genetic material. 4. The virus's genetic material detaches from the bacterium's genetic material and the bacterium produces the virus's proteins and genetic material. 5. New viruses assemble. 6. The bacterium bursts open, releasing new viruses.
The inner core of a virus is made up of genetic material that contains directions for creating new viruses.
DNA
Viruses are bits of genetic material, either DNA or RNA, that are covered in a protein sheath.
