Virus question for science?

Basically it attaches to the outside of the cell and encodes their cell in a cell they land on. It's been a while since I did this, so I don't want to go into too much detail in case I'm wrong.

Just Google "virus and host cell", "virus life cycle", "virus infects cell" or something similar. It will give you a decent answer.

Inside the nucleus of a cell is an area containing the DNA of that cell. This DNA is not only the building block of the cell, it is the instruction set that tells the cell how to behave. Think of it as the brain of the cell.

When a virus invades a cell it inserts itself on the outside of the cell and injects it's own DNA within the cell, replacing part of the cell's original DNA. This 'reprograms' the cell. The cell will continue to behave as instructed by the DNA sequences, but the new DNA sequences give the cell new instructions. As it happens these new instructions are the ones that instruct the cell to 'build' more of the virus.

Viral proteins can modify the functions of normal host proteins so that the proteins favor replication of the virus over normal cellular processes. Different viruses have different ways of doing this, and it gets real complicated real fast.

idk hmmm
