Why might scientists be interested in making transgenic organisms?
Transgenic organisms glow in the dark and provide a light source in dark places.
Transgenic organisms can produce a desired product that may benefit other organisms.
Transgenic organisms can be used to cut strands of DNA molecules into fragments.

Parkinson’s disease is a brain disorder that may be caused by mutations in several genes that code for the production of alpha-synuclein. Individuals who have Parkinson’s disease exhibit symptoms such as uncontrollable tremors, difficulty walking, and loss of coordination. How might geneticists determine where the mutations that cause Parkinson’s disease are located?
Which trait is determined by both genetics and the environment?
