The primary motor area is located in the frontal lobe, specifically the precentral gyrus or Brodmann area 4. Since the patient has lost motor activity on his right side of the body, then the more specific answer is the stroke is located in the left (contralateral because of decussation) frontal lobe, precentral gyrus.

lana66690 [7]

Explanation:

DNA is divided into functional units called genes. A gene is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA).
