| GO:0003968 | | RNA-directed 5'-3' RNA polymerase activity | | Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1); uses an RNA template, i.e. the catalysis of RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. |

In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes.

| GO:0008233 | | peptidase activity | | Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid. |
| GO:0004651 | | polynucleotide 5'-phosphatase activity | | Catalysis of the reaction: 5'-phosphopolynucleotide + H2O = polynucleotide + phosphate. |
| GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
biological process |
| GO:0006370 | | 7-methylguanosine mRNA capping | | Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript. |

| GO:0080009 | | mRNA methylation | | The posttranscriptional addition of methyl groups to specific residues in an mRNA molecule. |
| GO:0006397 | | mRNA processing | | Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. |
| GO:0008152 | | metabolic process | | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
| GO:0032259 | | methylation | | The process in which a methyl group is covalently attached to a molecule. |
| GO:0098507 | | polynucleotide 5' dephosphorylation | | The process of removing one or more phosphate groups from the 5' end of a polynucleotide. |
| GO:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
| GO:0039523 | | suppression by virus of host RNA polymerase II activity | | Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of host RNA polymerase II activity. |
| GO:0039657 | | suppression by virus of host gene expression | | Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of gene expression in the host organism. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Some protein processing events may be included when they are required to form an active form of a product from an inactive precursor form. |

| 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. |
