Pax-6 is a gene that is involved in eye formation in many invertebrates, such as Drosophila. Pax-6 is also found  in vertebrates. A Pax-6 gene from a mouse can be expressed in a fly and the protein (PAX-6) leads to a compound fly eye. This information suggests which of the following? a. PAX-6 proteins have identical amino acid sequences b. Pax-6 genes are identical in nucleotide sequence c. PAX-6 proteins are different for formation of different kinds of eyes d. Pax-6 is highly conserved and shows shared evolutionary ancestry

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.
