WebSo bacteria acquire genetic variation through random mutation, but, unlike humans or oak trees, they also regularly get new gene variants through the process of horizontal transfer … WebThey do have ribosomes because they have to code for proteins just like the rest of us do. Some of those proteins, they'll make some from-- bacteria, they'll make these flagella, which are tails that allow them to move around. They also have these things called pili. Pili is plural for pilus or pee-lus, so these pili.
