Delve into the microscopic world of viruses, learning about their structure, how they differ from living organisms, and their methods of infecting host cells. Understand the components of a virus, including nucleic acids (DNA or RNA), a protein coat called a capsid, and sometimes a lipid envelope. Explore how viruses, which cannot reproduce on their own, hijack host cells to multiply and spread, leading to infections in organisms.
