What is the meaning of polyhedral virus?

A polyhedral virus is a type of virus characterized by its geometric shape, typically resembling a polyhedron. These viruses have a symmetrical structure made up of protein subunits that form a closed shell, known as a capsid, which protects their genetic material.

Key Features of Polyhedral Viruses

• Shape: They often appear as icosahedrons, which have 20 triangular faces.
• Genetic Material: Their core can contain either DNA or RNA.
• Examples: Common examples include the adenovirus and the poliovirus.

Importance in Biology

Polyhedral viruses play significant roles in various biological processes, including disease transmission in plants and animals. Understanding their structure helps scientists develop vaccines and antiviral treatments.
