While characterizing a mutation in a gene of interest, you discover that the mutation involves an insertion within the coding sequence of the gene. You suspect that the inserted sequence is a transposon and would like to determine which of the three major transposon families it belongs to. What sequence elements could be looked for within the inserted sequence that would help place it in one of the three families?

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.
