These include alpha immediate early, beta early and gamma late. These immediate early genes are considered regulatory in nature. Beta early mRNA encodes for necessary viral enzymes and suppresses transcription of immediate early genes. The viral DNA is replicated in the nucleus. Nucleocapsids are formed and envelopment by budding from the nuclear membranes occurs.
Mature virions accumulate in vacuoles in the cytoplasm and are released by exocytosis or cell lyses.
Thus the replication cycle is completed.
