So I'm assuming you know that your DNA is basically a long chain of molecules with names starting with A, T, C, and G. And each one of those is bonded with another molecule in a complementary chain.
What's really going on is that your gene sequence is a long list of 3-letter chunks. Each one of those chunks has a protein associated with that floats freely in your cells. Those proteins, called translation RNA, have the complementary sequence of molecules on one side, and an amino acid on the other. That's what it means when you say that a 3-letter sequence "codes for" an amino acid: the corresponding tRNA molecule has that amino acid on the other side of it.
Your cells build little machines through the simple process of glomming together chains of amino acids. Not all of them are important for chemical reasons, some of them are important for their shape or structure.
Viruses are made of a very small number of molecules. There are probably like 10,000 in the entire thing. It'd almost be weirder if they were rounded and smooth, for the simple reason that there are not enough molecules to get a smooth surface.
Biology is absolutely insane and I am constantly awed by how amazing the natural world is.
