![]() Protein production is thus slowed down or stopped altogether, and the cell ceases to function properly (or at all). The adverse effect of the virus comes from the fact that while the replicator is busy with photocopying the virus, it does not process the "normal" RNA which comes from the cell's own genetic code. The virus is sufficiently small to enter some cells, where it hijacks the replicator engine, which makes other copies of the virus, by which the attack spreads. ![]() Proteins are the active molecules which do all the work to keep a cell "alive". RNA then goes through some "engines" which can duplicate it and/or convert it into proteins (genetic code is really blueprints for proteins). RNA is an intermediary vessel for genetic code, which temporarily duplicates a piece of the DNA (the permanent storage of genetic information in a cell). The difference is mostly a matter of historical tradition.īiologically, a virus is a piece of RNA.
