A disease is caused by having no functional protein produced from the kip gene. An individual has this disease but has no mutation in the kip gene. You look at other gene candidates that could result in no functional kip protein. A gene called D5 codes for a methyltransferase that methylates the kip promoter region. A gene called T3 codes for an acetylase that acetylates the histones in the region of the kip gene. Fill in the following blanks. In the situation described above, in which no kip protein is made, it is likely that the D5 gene has a mutation that ___________ the D5 protein or that the T3 gene has a mutation that ___________the T3 protein.   Blanks can either be deactivates or activates

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.
