Motor neurone disease or more commonly known as amyotrophic lateral sclerosis is a genetic disorder that targets the motor neurones of the human nervous system. More specifically the disease targets the movement aspects of the human body by slowly degenerating the motor neurones located in the spinal cord.

Contained within the structure of DNA are chromosomes. These chromosomes determine many of the genetic instructions that are within the human body. However these chromosomes…
