There are dozens of common variations of the c-myc gene, which are associated with different types of cancer. Here are 3 variations of part of a sequence of the c-myc gene, located between nucleotides 180 and 201. The original sequence is given to you, as well as the sequences of 3 variations. The mutated nucleotide of each variation is annotated in gray. Use this information (picture) to answer the next two (2) questions  1. Which of the c-myc variations is least likely to cause a change in c-myc function? 2. Which variation of c-myc produces a nonsense mutation?

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.
