The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class I protein complex following intracellular transport via a TAP (transporter associated with antigen processing) pathway. The peptide is typically a fragment of a larger exogenous protein which has been degraded within the cell and is dependent on TAP transport from the cytosol to ER for association with the MHC class I molecule. Class I here refers to classical class I molecules.

The repair of a double-strand break in DNA in which the two broken ends are rejoined with little or no sequence complementarity.

These in turn may further branch into sub-pathways, but evidence is still unclear.
