Virus particles that house large DNA genomes are structurally much more intricate than any considered in previous sections. Such particles comprise obviously distinct components with different symmetries and/or multiple layers and in some cases exhibit architectures that do not appear to be based on helical or icosahedral symmetry. In this section, we illustrate various ways in which multiple structural elements can be combined. As we shall see, some of these elements are dedicated to specific functions.
