macromolecule biosynthetic process RNA metabolic process RNA biosynthetic process GO:0032774 Note that, in some cases, viral RNA replication and viral transcription from RNA actually refer to the same process, but may be called differently depending on the focus of a specific research study. RNA anabolism RNA biosynthesis RNA formation RNA synthesis The chemical reactions and pathways resulting in the formation of RNA, ribonucleic acid, one of the two main type of nucleic acid, consisting of a long, unbranched macromolecule formed from ribonucleotides joined in 3',5'-phosphodiester linkage. Includes polymerization of ribonucleotide monomers. Refers not only to transcription but also to e.g. viral RNA replication. biological_process nucleobase-containing compound biosynthetic process
