Does viruses contain DNA?
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 .
Some viruses contain RNA; these are known as retroviruses. Others contain DNA.
An organism is not "nonliving." Many biologists consider viruses to be non-living. Many viruses contain DNA.
Pneumonia is inflammation of the lung disease. It can be caused by bacteria or viruses. Most of the time, it is bacterial (which contain DNA). Viruses can be RNA or DNA-based.
Viruses contain either DNA or RNA.
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.
Both plant and animal cells and viruses contain RNA. Some viruses contain DNA but not both DNA and RNA. Animal and plant cells contain both RNA and DNA.
Yes. Anything that isn't an organism will not contain DNA. For example, rocks do not have DNA. Additionally, some viruses have RNA instead of DNA although viruses would be covered by the first category mentioned.
Retro Viruses contain RNA
Infuenza Virus Contain Both DNA and RNA. No other Virus show such characteristics.
Directly, viruses mostly contain RNA used for replication in the host cell.
No. They contain one or the other not both.
defense against viruses....to protect their own DNA from the viruses
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 do not contain DNA or RNA . . . they 'steal' those molecules from their host living cell.
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.
Cells are considered "living". Viruses are not because they require a host body to reproduce and perform living functions such as reproducing, creating ribosomes, etc. Cells contain RNA and DNA, as does viruses. However viruses may not contain both DNA and RNA, only one.
All living things contain DNA, including viruses, bacteria and of course cactus plants
All organisms have DNA. Retroviruses contain only RNA, but viruses aren't strictly "organisms".
Viruses have either a DNA nucleic sequence OR a RNA nucleic sequence
Only Influenza virus Contains Both ..
They all contain DNA in there genetic material
They need either DNA or RNA.
They have genetic materials. They have DNA or RNA
Viruses are noncellular organisms that contain only DNA or RNA sequences enclosed in a coat of proteins.
Some viruses contain only RNA (and need a host with DNA in order to replicate themselves). Red blood cells of mammals are anucleated (lack a nucleus) and do not contain nuclear DNA as a result.
I only know of a few viruses, (which aren't even cells) that contain RNA but no DNA. As far as I know all cells contain DNA as their genetic blueprint and RNA to do the work.
Different kinds of viruses can contain either DNA or RNA. This is encapsulated in a protein shell. Some viruses are also enclosed in a lipid bilayer, like cells.
No. They only contain a nucleic acid, either RNA or DNA, and some proteins.
They are in their genetic materials. They have either DNA or RNA
Yes. Viruses contain a protein coat called a capsid. Inside this capsid will be DNA or RNA but never both. Viruses that contain RNA are called retroviruses. They also contain the enzyme reverse transcriptase that allows them to convert RNA into double-stranded DNA once it infects a cell.
In eucaryotes, DNA is only found in the nucleus of most cells, mitochondria and chloroplasts. In procaryotes, DNA is found in the cytoplasm in an area known as the nucleoid and in small, circular pieces of DNA called plasmids. Some animal viruses, plant viruses, and bacteriophages also contain DNA.
There are several differences for example; most DNA viruses use the DNA polymerases of of the host cell to synthesize new genomes along the templates provided by the viral DNA, in contrast to replicate their genomes, RNA viruses use virally encoded polymerases that can use RNA as a template. RNA viruses usually retain their RNA within capsids, whilst DNA viruses are less "packaged" usually retained within say a head, or a capsomere. The main difference… Read More
Viruses are non-living organisms. They only become living once they enter a host cell. Viruses are non-living originally as they only contain either DNA or RNA, while living organisms contain both.
Although they both both contain RNA & DNA and both cause diseases. Bacteria is living and viruses are not. Viruses need a host cell to reproduce.
They are (double stranded) DNA viruses.
Examples include: - Influenza - HIV - Hep C
they cannot replicate on their own, although they do either contain DNA or RNA
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Living cells also contain DNA and RNA. These are the only thing shared by living cells and viruses.
DNA (deoxyribonucleic acid) is found in all living things (note though that viruses may contain RNA instead, it is not yet decided as to whether viruses are living or non living). Blood is a complex of red blood cells, white blood cells, and a straw coloured fluid. It is the blood cells that contain DNA as DNA is found in every cell of the body.
Yes. Viruses contain either DNA or RNA, but that does not mean they are alive, as they are not composed of cells.
bacteria causes viruses 2nd Answer: My apologies, but the first answer is totally untrue. Both bacteria and viruses can cause disease, but bacteria are alive, and viruses are not. They both contain RNA/DNA to assure they are replicated correctly.
yes! Virus contains both DNA and RNA some viruses contain RNA as their geneti information and are called retroviruses.when retroviruses infect a cell, they produce a DNA copy of their RNA.
Yes. Although not both together, a virus contains a nucleic acid, either single stranded or double stranded DNA or RNA.
viruses are genetic elements that contain DNA or RNA as their genetic material,and have an extracellular form. Plasmids do not have an extracellular form. Plasmids only have DNA.
Of course a virus is bigger. Viruses contain DNA which is a polymer made up of many molecules.
Viruses that are made of DNA use the host cell's enzymes to synthesize the RNA needed to synthesize viral proteins. Viruses that contain RNA have an enzyme called reverse transcriptase which they can use to synthesize DNA from an RNA template. Thus, they don't need to have both.
In most cells (viruses are an exception) DNA codes for protein and mRNA. Some viruses contain RNA which in turn codes for DNA and proteins, although I do not think they would be called units of heredity.
protein synthesis, translation. and transcription. Some viruses contain RNA instead of DNA. These viruses have an enzyme called reverse transcriptase. The virus then uses the host cell to produce DNA from the RNA using reverse transcriptase.
Smallpox contains DNA Smallpox is a virus, and therefore, can only have RNA or DNA. In the case of smallpox, it contains DNA. Viruses require a host to supply them with either RNA or DNA in order that more virus entities can be made. DNA
These do not have that much in common. Not all are small (fungi and algae), not all are green (algae), not all are even alive (viruses) nor do all contain DNA (viruses).
