Heteroployploidy is seen in which viruses?
- Enveloped RNA Viruses
Phenotypic Mixing is seen in which viruses?
What type of mutation yields extreme genetic masking?
Viral Replication occurs where?
- RNA: Cytoplasm
- DNA: Nucleus
What enzyme is responsible for NA replication/mRNA synthesis?
_NA-Dependent _NA Polymerase
Steps in viral replication
- Synthesis of Viral Compnents
Types of Penetration:
Period before the start of viral nucleic acid replication.
- Period after the start of viral nucleic acid replication.
- Early gene:
- Viral genes that express before nucleic acid replication
Early Genes encode for….
… enzymes or factors that help in virus replication.
Viral genes that express after nucleic acid replication
Late Genes encode for…
…viral structural proteins and factors for virus assembly.
Attachment, penetration and uncoating have taken place. Synthesis of viral components may have started, but viral assembly has not yet started.
Get out of the cell
Loss of virus infectivity.
