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 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.
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 a species jumper?
a virus capable of infecting other species
What is viral emergence?
A virus that has suddenly appeared or has recently come to the attention of medical scientists.
How does a virus maintain it's environment?
yess the air not awair of thair sarodigs thoue
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 effects can mutation have a virus?
They create genetic variations.
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.
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
What do projections on a virus allow it to do?
They allow virus to fix to the host.They help to invade host.
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 is a species jumper?
a virus capable of infecting other species
What is needed for the virus to jump from species to species?
they drink the same water
What is viral emergence?
A virus that has suddenly appeared or has recently come to the attention of medical scientists.
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.
