- Exocrine
- Refers to glands that deposit their secretion(s) into ducts that drain to the "exterior". [discussion] [view topology] Compare endocrine.
- Exocytosis
- Exon
- Portion of a gene that is retained in the messenger RNA (mRNA) molecule. Adjacent exons are separated from each other by introns. Often exons encode one domain of a protein. The ability to shuffle exons in different combinations may — over the course of evolution — have speeded up the creation of new genes with new functions. [More]
- Exosome
- Term unfortunately used for two entirely-different cell structures: (1) tiny vesicles released by the cell for various types of cell-to-cell signaling [View], e.g., antigen presentation, and (2) complexes used for RNA degradation.
