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.
What are central to the life cycle of a virus are the types of nucleic acids formed during its replication and the pathway by which mRNA is produced. The relation between the viral mRNA and the nucleic acid of the infectious particle is the basis of a simple means of classifying viruses.
