Watson_strand
SO:0002262
Definition: An absolute reference to the strand. When a chromosome has p and q arms, the Watson strand is the strand whose 5'-end is on the short arm of the chromosome. Of note, the term 'plus strand' is typically based on a reference sequence where it's preferred for the plus strand to be the Watson strand, but might not be and 'plus strand' is therefore not an exact synonym.

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.
