The two brains shown below are of a normal brain (left) and a brain from an individual with Huntington’s disease (right). Huntington's disease is a rare inherited disease in which there is a progressive breakdown of nerve cells in the brain. Huntington's disease occurs when there is a defective gene, and therefore a defective protein. Which of the following THREE statements are TRUE?
The Huntington protein is coded for by a gene within the DNA of the human genome
The gene for Huntingtons is found only in the DNA of the brain cells in the body and is expressed when present
All cells have DNA
Not all cells have DNA
A mutation in the Huntington's gene could cause changes in the structure of the proteins which would change their ability to function
Based on your knowledge of structure and function and the image below, explain what a mutation is and how they can affect the structure and function of proteins. Use two pieces of evidence from the image to support your explanation.
