Large scale study of proteins that contain the genetic material?
You might need to re-phrase your question. At the moment it sounds like you're talking about viruses?
What genetic material in viruses?
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.
What are the features virus and typical plant cell have in common?
AnswerThey do reproduce but a virus can't reproduce outside of a host cellso the only thing in common really is that the virus needs a cell to reproduceThe only real similarity between viruses and living cells are that they both have some sort of genetic material. Cells have DNA and viruses have either RNA or DNA. But since viruses cannot reproduce on their own (because they are non-living) they need to reproduce by inserting their genetic material into living cells.
What is a charectristic of a virus?
All viruses are sharing a common feature that their genetic material DNA or RNA in packed in a protein coat capsid. Enveloped viruses may contain glycoproteins on their envelope (eg:HIV). Virus can not replicate or reproduce themselves, they need to infect their host and integrate their genome into the host for its replication.
What are two ways viruses are like living things?
The only characteristic of a living thing that is shared by viruses is genetic material, either DNA or RNA. They do not reproduce, their genetic information hijacks a living cell's machinery, and turns the cell into a virus factory, this is called replication. They do not require food. Some viruses have moving parts that allow them to inject their genetic material into the host cell.
What are the two main structures of a virus?
Viruses have a particular character that they need a living host to survive or they cannot otherwise live. Generally viruses have a capsid which has its viral RNA enclosed in it. Capsid is covered by thick membrane.
Do viruses need oxygen to live?
No, viruses are not living organisms and do not require oxygen to survive. They are simply comprised of genetic material (DNA or RNA) enclosed within a protein coat, and they rely on host cells to reproduce.
What would happen if the nucleus didn't have genetic materials?
A cell cannot function without genetic material (with the exception of red blood cells, which do function without genetic material - all they have to do is to contain hemoglobin and float in the blood as it circulates). However, in organisms called prokaryotes the genetic information is not present in the nucleus but in the cytoplasm. This is possible because their genetic material is very simple and does not need the nucleus to protect it from harm.
How are viruses used for gene therapy?
The news about viruses isn't all bad. In a technique called gene therapy, scientists take advantage of a virus's ability to enter a host cell. They add genetic material to a virus and then us the virus as a "messenger service" to deliver the genetic material to cells that need it.

What viruses cannot?
They can not reproduce without a host as reproductive vector. They have no metabolism and do not preform cellular functions. Viruses are genetic material enclosed in a protein capsid.
Where is genetic material stores?
You need to specify in which city and in which country
Why are viruses intracellular?
Viruses are intracellular because they need to hijack the cellular machinery of a host cell in order to replicate and produce more virus particles. They cannot replicate on their own and rely on host cells to multiply. Once inside a cell, a virus releases its genetic material and uses the host cell's resources to replicate.
