biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |

|
biological process involved in interspecies interaction between organisms
|
Any process evolved to enable an interaction with an organism of a different species. |
|
GO:0051701
|
biological process involved in interaction with host
|
An interaction between two organisms living together in more or less intimate association. The term host is used for the larger (macro) of the two members of a symbiosis; the various forms of symbiosis include parasitism, commensalism and mutualism. |
|
GO:0044403
|
biological process involved in symbiotic interaction
|
A process carried out by gene products in an organism that enable the organism to engage in a symbiotic relationship, a more or less intimate association, with another organism. The various forms of symbiosis include parasitism, in which the association is disadvantageous or destructive to one of the organisms; mutualism, in which the association is advantageous, or often necessary to one or both and not harmful to either; and commensalism, in which one member of the association benefits while the other is not affected. However, mutualism, parasitism, and commensalism are often not discrete categories of interactions and should rather be perceived as a continuum of interaction ranging from parasitism to mutualism. In fact, the direction of a symbiotic interaction can change during the lifetime of the symbionts due to developmental changes as well as changes in the biotic/abiotic environment in which the interaction occurs. Microscopic symbionts are often referred to as endosymbionts. |

|
viral life cycle
|
A set of processes which all viruses follow to ensure survival; includes attachment and entry of the virus particle, decoding of genome information, translation of viral mRNA by host ribosomes, genome replication, and assembly and release of viral particles containing the genome. |
|
GO:0016032
|
viral process
|
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. |
|
GO:0019068
|
virion assembly
|
A late phase of the viral life cycle during which all the components necessary for the formation of a mature virion collect at a particular site in the cell and the basic structure of the virus particle is formed. |
|
GO:0035891
|
exit from host cell
|
The movement of an organism out of a cell of the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction. |
|
GO:0039674
|
exit of virus from host cell nucleus
|
The directed movement of the viral genome or a viral particle out of the host cell nucleus. |
|
GO:0046802
|
exit of virus from host cell nucleus by nuclear egress
|
The directed movement of an assembled viral particle out of the host cell nucleus by budding and fusion through the nuclear membranes. In this process, enveloped viral particles are formed by budding through the inner nuclear membrane. These perinuclear enveloped particles then fuse with the outer nuclear membrane to deliver a naked capsid into the host cytoplasm. |
|
GO:0046755
|
viral budding
|
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. |
|
GO:0046765
|
viral budding from nuclear membrane
|
A viral budding that starts with formation of a membrane curvature in the host nuclear membrane. |
|
GO:0046771
|
viral budding from inner nuclear membrane
|
The envelopment of a virus, in which the nucleocapsid evaginates from the host inner nuclear membrane system into the perinuclear space, thus acquiring a membrane envelope. |
