Capsids
Capsids are protein coats that surround and protect the genetic material of viruses. They are composed of multiple protein subunits arranged in a highly organized structure. Capsids play a crucial role in the virus life cycle, aiding in the attachment to host cells, facilitating entry into the cell, and protecting the viral genome from degradation. The structure of capsids can vary greatly among different viruses, influencing their ability to infect and replicate within host cells.
