  • proteins
  • Immediate early gene transcription occurs in the first 4 hours following viral infection, when key regulatory proteins that allow the virus to take control of cellular machinery are made. (medscape.com)
  • The late gene products are made approximately 24 hours after infection, and these proteins are chiefly structural proteins that are involved in virion assembly and egress. (medscape.com)
