Viral Replication
For multiplication or replication, virus totally depend on host cell, because viruses lack enzymes required for multiplication.
Information of virus multiplication prevent in viral nucleic acid (RNA/DNA).
Stages of Viral Replication
1. Attachment
2. Penetration
3. Uncoating
4. Replication
5. Assembly
6. Maturation
7. Release
Viral Multiplication Cycle
1. Attachment to host cell
2. Penetration
Penetrates into host cell.
3. Uncoating
Uncoated viral nuclei integrates into host DNA.
4. Biosynthesis
Synthesis of various molecule that are required for formation of virus.
5. Assembly or maturation
After biosynthesis, biomolecules assemble; formation of complete virus).
6. Release
Release out of host cell, time taken for viral multiplication is about 25-30 hour's.
