Structure of viruses MDCAT Quiz with Answers

The viruses have a simple but highly specialized structure for their ability to infect the host cells. The two major components of viruses are genetic material and a protein coat, on the other hand called capsid. Genetic material may either be DNA or RNA; however, it carries information required to replicate the virus in the host cell. Capsid or protein coat, on the other hand, protects the genetic material and is composed of several protein subunits known as capsomers. In a few viruses, besides this basic structure, there is an outer lipid bilayer derived from the host cell membrane; it is called an envelope. The envelope contains spike proteins, which play a very important role in the recognition of the virus and entry into the host cells. The viral structure, therefore, determines the way in which the viruses interact with the host cells and is very vital in viral classification. The knowledge of viral structure is important to MDCAT students in answering questions about viral replication, transmission, and treatment.

Test Your Knowledge with an MDCAT Quiz
An MDCAT Quiz on the Structure of Viruses will help to strengthen your understanding of viral components, including the capsid, genetic material (DNA or RNA), and envelope. The types of viruses according to their structural characteristics are icosahedral, helical, and complex viruses. Regular practice through these quizzes enables one to understand how viral structure interlinks with its ability to infect and replicate within a host cell, thus preparing for the MDCAT exam.
