WebSep 14, 2024 · The structure of viruses was covered during the lessons in topic 2.1, so this lesson starts by challenging the students to recall the capsid, genetic material in the form of viral RNA and the lipid envelope. WebA virus has a shell that contains it's RNA, and reproduces by hi-jacking a normal cell's mechanisms. A prion is a protein, with no shell, that catalyzes (encourages) other proteins to fold the same way as the prion, without using RNA or a cell's reproductive mechanisms. 3 comments ( 36 votes) Show more...

WebViruses usually inject their all genetic material into one cell, which helps to spread disease through is assembly and release of new viruses from the first infected cell. Sometimes … WebEach virus is a nucleic acid (RNA or DNA) surrounded by a coating, referred to as an envelope or capsid. Viruses encode capsid proteins which encase the nucleic acid. Sometimes, viral proteins combine with host proteins to make the envelope. The shape of a viral coat has implications on how a virus infects a host.
