Answer:
At a level in the spinal cord
Explanation:
The gate theory was elaborated in 1965 by P.D. Wall and r. Melzack, to explain the influence of tactile skin stimulation on pain relief. It essentially admits that there exists in the medullar posterior horns (located behind the central canal of the spinal cord) a gate-acting neural mechanism that can control the passage of nerve impulses transmitted from the peripheral fibers to the CNS through the medulla.
The gate regulates the influx of nociceptive impulses even before a perception of pain is created. The variation in the passage of action potentials (nociceptive) that the gate produces is determined by the activity of the thick (A-alpha and A-beta) and thin (A-delta and C) fibers, as well as cognitive influences.
Correct answer: C). Thymine
The thymine, which is present in the DNA is replaced by the uracil in the RNA. Uracil is one of the four nitrogenous bases which are found in the RNA. The nitrogenous bases present in the RNA are adenine, guanine, uracil, and cytosine. While the nitrogenous bases found in DNA are Adenine, guanine, thymine, and cytosine.
Hence, thymine is the nitrogenous bases which are not found in RNA.
