Rather more easily than mutations in your genome! A virus which may have only a few hundred genes can have large changes in function from just one mutation and can be then accounted a new "species " as progeny inherit the mutation. ( as much as one counts viruses as species )

What do projections on a virus allow it to do?
They allow virus to fix to the host.They help to invade host.
What is sequential mutation?
It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.

How does a new strain of a virus form?
Through mutation of an existing virus into new forms. Usually, there is mutation of the protein coating of the virus that results in a new strain. The new strain may or may not be infectious to the same group or organism that was vulnerable to the original virus strain. For a case example of how new viruses form, see the related question below that explains in detail what caused the new 2009 Pandemic Swine Flu virus. Also see the related question about the Lytic Cycle, which is the process that viruses use to attach to cells and reproduce.
What is the genus and species category for influenza?
it is a negative single strand RNA virus of family orthomyxoviridae having four group: influenza A, influenza B, influenza C, and thogoto virus. containing 7to 8 segments of linear rna with a genome length b/w 12,000 to 15,000.
What is a sentence with the word mutation?
The mutation of the virus made the vaccines useless.Other than evolution, species can also change through mutation.By triggering the mutation of the genes, we created a super soldier.
Can fairies get aids?
No. Fairies are such a distant species that the aids virus cannot (at this time) effect a cross over.
What might be an effect of a mutation in a virus?
Most of the time, a mutation in a virus results in better ability to infect a host cell and more resistance to the host cell's defenses.
What effects can mutation have a virus?
They create genetic variations.
Why must pharmaceutical companies develop flu vaccines every year?
Influenza is an RNA virus. Being that it is an RNA virus it has a high rate of mutation that goes unchecked. This high rate of mutation leads to different strains of the influenza virus
How can variation occur in species that dont reproduce sexually?
Randomly and naturally occuring mutation. A virus might also inject some DNA into their spores or something as well.Bacteria take in DNA fragments from their environments.
What do projections on a virus allow it to do?
They allow virus to fix to the host.They help to invade host.
What is sequential mutation?

How virus mutation is like Darwin's concept of adaptation?
Virus mutation is akin to Darwin's concept of adaptation in that both involve changes in the genetic makeup of a population over time to better suit the environment. Mutations in viruses can lead to new characteristics that may provide them with a survival advantage, similar to how natural selection drives adaptation in species. Ultimately, both processes result in the emergence of better-adapted individuals that are more likely to survive and reproduce.
What parts of a virus allow it to attach to a cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
What is needed for the virus to jump from species to species?
they drink the same water
What are ways for malware authors to get around antivirus engines?
Some methods they use are: Stealth mode - the virus intercepts requests from the anti-virus program and returns the information the anti-virus program would expect from a non-infected program. Self-modification or mutation - the program changes its code slightly with each infection to make it harder for anti-virus software to create a "signature" for the virus Encryption of the payload - this may obfuscate the actual virus, especially if a different encryption key is used each time. The code still has to have a decrypting function attached to allow the virus to unpack and execute. Polymorphic viruses - this is sort of a combination of the encryption and mutation tactics. The virus payload is encrypted and the decrypting function modifies itsself with each infection to make it very tough to create a signature for the virus.
