Question

Endorphins are polypeptides that reduce pain. What is the amino acid order for the endorphin methionine enkephalin(met-enkephalin), which has the following mRNA.

AUG  UAC GGU GGA UUU AUG UAA

Step-by-Step Solution

Answer

The order of met-enkephalin is START-Tyr-Gly-Gly-Phe-Met-STOP.

Step 1: Given information

We have been find out what is the amino acid order for the endorphin methionine enkephalin(met-enkephalin), which has the following mRNA.

Step 2: Explanation

Endorphins are polypeptides that reduce pain. 

 The order of met-enkephalin is START-Tyr-Gly-Gly-Phe-Met-STOP.

AUG corresponds to Methionine amino acid,  

UAC corresponds to Tyrosine amino acid, 

GGU corresponds to Glycine amino acid, 

GGA corresponds to Glycine amino acid, 

UUU corresponds to Phenylalanine amino acid,   

AUG corresponds to Methionine amino acid,

UAA corresponds to Glutamine amino acid,
