Answer:
The molecular structure of complex macromolecules show that a chemical reaction has occurred.
Explanation:
A macromolecule is defined as molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
Macromolecules are formed by chemical reactions between simple molecules which join together to give the macromolecule.
If we look at the structure of a macromolecule very closely, we will discover evidences that show that the complex structure of the macromolecule was created by stepwise chemical reactions.
Answer:
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
DNA is the bio molecule that contains all of the organisms genes. when cell divides through mitosis, the daughter cells contains exact copies of DNA from both of its parents.

Sensory neurons are the neurons responsible for receiving the information from the environment or the stimuli. This sensory neurons pass the message thru interneurons and then to Central Nervous System (brain and spinal cord) which then sends the signal to the motor neuron. </span>
