Definition: A genomic island is an integrated mobile genetic element, characterized by size (over 10 Kb). It that has features that suggest a foreign origin. These can include nucleotide distribution (oligonucleotides signature, CG content etc.) that differs from the bulk of the chromosome and/or genes suggesting DNA mobility.

Comments and references

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.
