A Multi Organism Process in Which a Virus Is a Participant. the Other Participant Is the Host. Includes Infection of a Host Cell Replication of the Viral Genome and Assembly of Progeny Virus Particles. in Some Cases the Viral Genetic Material May Integrate Into the Host Genome and Only Subsequently Under Particular Circumstances 'complete' Its Life Cycle.
A Viral Process by Which Enveloped Viruses Acquire a Host Derived Membrane Enriched in Viral Proteins to Form Their External Envelope. the Process Starts When Nucleocapsids Assembled or in the Process of Being Built Induce Formation of a Membrane Curvature in the Host Plasma or Organelle Membrane and Wrap Up in the Forming Bud. the Process Ends When the Bud Is Eventually Pinched Off by Membrane Scission to Release the Enveloped Particle Into the Lumenal or Extracellular Space.
Double Layer of Lipid Molecules As It Encloses Host Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. the Host Is Defined As the Larger of the Organisms Involved in a Symbiotic Interaction.
