WebbViruses do, however, have a few key features in common. These include: A protective protein shell, or capsid A nucleic acid genome made of DNA or RNA, tucked inside of the capsid A layer of membrane called the envelope (some but not all viruses) Let's take a closer look at these features. Image modified from " Scheme of a CMV virus ." Webb24 aug. 2024 · A capsid is a protective coat of protein that protects the genetic material of the virus. Capsids can be identified in three different shapes: icosahedral, helical, and prolate. Most viruses are icosahedral and helical in shape. But, some viruses such as bacteriophages have more complicated shapes. The capsid is made up of proteins.

WebbFimbriae (sing. fimbria) Fimbriae are thin filamentous appendages that extend from the cell, often in the tens or hundreds. They are composed of pilin proteins and are used by the cell to attach to surfaces. They can be particularly important for pathogenic bacteria, which use them to attach to host tissues.
