primary_transcript

SO:0000185

Definition: A transcript that in its initial state requires modification to be functional.

Comments and references

See "precursor_RNA" (SO:0002393) for RNA which may be the result of post-transcriptional processing. If the RNA in question is known not to have been processed, use this class ("primary_transcript"). On 9 Sep 2025, Removed "has_exact_synonym : INSDC_feature:precursor_RNA" and "has_exact_synonym : precursor RNA" from the annotation for this class at the request of Terence Murphy of NCBI. See GitHub Issue #655.

Change history

This timeline summarizes changes identified in SO’s GitHub commit history, including updates to labels, definitions, parent terms, synonyms, subsets, and obsoletion status. It is a best-effort reconstruction and may not include every change to a term. Since only history from GitHub is included at the moment, any term added before the migration from SVN to Git will show as being created in 2016. This will be addressed once SVN history is incorporated.
