Capsid of the virus can be defined as the protective covering made of proteins. The main function of capsid is to protect the genetic material of the virus and also provides attachment to the host cell.
If a drug is taken that destroys the capsid of virus, then the genetic material of the virus would be cleaved and it would not be able to replicate and infect the host cell.
