A receptor refers to a protein molecule, which attains chemical signals from external of a cell. The receptor proteins are categorized by their location. On the other hand, the structural proteins refer to the fibrous proteins. One of the essential activity of the structural protein is to maintain the configuration of the cell.
In the nerve cells, the receptor proteins pick up signals of pain and structural proteins helps in maintaining the shape and configuration of the nerve cell.

Attached is an example of a mRNA wheel.
The codon UAA codes a stop codon. The mRNA wheel is read by starting to choose from the four letters at the centre the one that is the first in the codon. Then, on that quarter of the circle, choose from the four letters, the second in the codon. Repeat again the process for the 1/16 part you chose previously choosing now the last letter in the codon. You are now able to identify what is coded by the mRNA codon.
