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.
Embedded in the viral envelope are proteins from the host cell, as well as 72 copies (on average) of a complex HIV protein (frequently called spikes that protrudes through the surface of the virus particle (virion).he capsid surrounds two single strands of HIV RNA, each of which has a copy of the virus's nine genes. Three of these genes, gag, pol, and env, contain information needed to make structural proteins for new virus particles.
