I didn’t know that they were! I’ll look into this one for you… I thought that they looked like those weird toys that are spherical, with bits sticking out of them, that bounce and wobble about… There must be different shapes depending on their purpose. I’ll read up on it for you – unless the boys beat me to it! I’ve got my Departmental Ball tonight, so answers will be late tonight, sorry! 🙁
Suze is right, there are different shapes of virus. Some have “legs” to grab hold of cells and inject there DNA. others are round, which have spikes to stick to cells and help them be absorbed into the cells.
