Although the cause of Parkinson's disease is unknown, research indicates that it may be due to defective nuclei in the cells of those affected. Which of these could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson's? es ) A) Enzymes could no longer be produced B) DNA could not be accurately replicated Mitochondria could no longer produce ATP D) Transport across the membrane would be decreased

B) DNA could not be accurately replicated

Explanation:

Parkinson's disease is characterized by a deficiency in movement due to an anomaly in the nervous system of the body. However, according to this question, the cause of Parkinson's disease is unknown, although research points out that it may be due to defective nuclei in the cells of those affected.

Since Parkinson's disease is considered to be related to a defective nuclei at the cellular level, the most likely result is that DNA could not be accurately replicated. This is because DNA is located in the nucleus, and hence, a defective nucleus will affecti the DNA.

N.B: The other options are not related to the nucleus

a, i am pretty sure.
