The occipital lobe is the area of the brain that a stroke would affect to mimic damage to cranial nerve 2.
We can arrive at this answer because:
Cranial nerve 2 is the optic nerve, responsible for visual information.
This nerve is directly connected to the occipital lobe.
In this case, when a stroke affects the occipital lobe, cranial nerve 2 can be affected and if this happens the optic nerve will have problems.
Optic nerve problems can cause defects in the field of vision, impede centralvision, not allow the eyes to focus on a particular element, and have centrocecal or altitudinal problems.
Answer:Silent mutations arise while the alternate of a single DNA nucleotide inside a protein-coding part of a gene does now no longer have an effect on the series of amino acids that make up the gene's protein.
