Italy, though an Allied Power during World War I, joined the Axis Powers under the leadership of Benito Mussolini, only to depose Mussolini in 1943 and fight the German occupation of their northern territories. The inclusion of Japan into the Axis Powers made China join the Allied Powers.
Lecture 2: Virus Structure. All viruses contain the following two components: 1) a nucleic acid genome and 2) a protein capsid that covers the genome. Together this is called the nucleocapsid. In addition, many animal viruses contain a 3) lipid envelope.
Viral Capsids and Envelopes: Structure and Function. Abstract. Virus particles contain the viral genome packaged in a protein coat called the capsid. For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells.
