You can get my books here: https://stevemould.com/books This is a bunus video on top of my usual schedule and it's a little different to what I normally make. But don't worry, I'm not turning into a kids' channel! Normal service will resume on my next video. In light of coronavirus, I wanted to make a straightforward video that explains viruses in simple terms that kids (and adults!) can understand. It's also an introduction to cells and the molecular machinery inside. It covers DNA, RNA, membrane fusion and how viruses get from one person to another.
