Mutation: Thiamine Dimers A. what is a mutagen or cellular process that leads to this mutation? B. If the nucleotide excision repair pathway is not functional, is there another pathway or mechanism for preparing this mutation? if so, what is the pathway/mechanism?

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
