The progression of the beak over time from its initial formation until its mature state. The avian beak is an external anatomical structure, in the head region, that is adapted for feeding self and young, catching prey, probing, etc. It encompasses, but is not restricted to, the maxilla, mandible, maxillary rhamphotheca, mandibular rhamphotheca, nostril, nasal fossa, nasal bones, egg tooth and rictus.

Viral interference in host cell processes that lead cell cycle arrest, allowing cell division to occur.

OBSOLETE. Any viral process that results in the inhibition of complement neutralization of the host cell.

Binding to a double-stranded DNA region containing a single guanine insertion or a deletion that results in an unpaired guanine.

Binding to a double-stranded DNA region containing a single cytosine insertion or a deletion that results in an unpaired cytosine.

A homodimeric protein complex that possesses 4-aminobutyrate transaminase activity.

Binding to a double-stranded DNA region containing a single thymine insertion or a deletion that results in an unpaired thymine.

Binding to succinate-semialdehyde dehydrogenase.

Any process that initiates the activity of the inactive enzyme protein kinase B.

Binding to a double-stranded DNA region containing a single adenine insertion or a deletion that results in an unpaired adenine.

Any viral process that interferes with and inhibits the assembly and function of polysomes.

The addition of tubulin heterodimers to one or both ends of a microtubule.

The directed movement of intronless viral mRNA from the host nucleus to the cytoplasm for translation.

The chemical reactions and pathways resulting in the formation of a macromolecule destined to form part of a membrane in a cell.

The process of restoring viral DNA after damage or errors in replication.

The process of organizing and assembling viral replication proteins in preparation for viral replication.

The chemical reactions and pathways resulting in the breakdown of misfolded proteins transported from the endoplasmic reticulum and targeted to cytoplasmic proteasomes for degradation.

Binding to a receptor on the host cell surface.
