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.

Question

Describe some mutation repair mechanisms.

Expert Solution

Step 1

Mutations are the change in the genetic sequence of the individual due to external factors. If these factors are naturally occurring the type of mutation observed is spontaneous mutation. If the factors are introduced in the genome those type of mutations are called induced mutations. The mutation resulting factors are commonly termed as mutagens.

Some mutations have deleterious effects while some have advantageous effects. It's the responsibility of the cell to prevent and harmful mutation by conducting repair mechanism.
