NURSING ANM AND GNM

Detailed explanation-1: -The 20 to 22 amino acids that comprise proteins include: Alanine. Arginine. Asparagine.

Detailed explanation-2: -Roughly 500 amino acids have been identified in nature, but just 20 amino acids make up the proteins found in the human body. Let’s learn about all these 20 amino acids and the types of different amino acids.

Detailed explanation-3: -There are 22 amino acids that are found in proteins and of these, only 20 are specified by the universal genetic code. The others, selenocysteine and pyrrolysine use tRNAs that are able to base pair with stop codons in the mRNA during translation.

Detailed explanation-4: -Since each of the 20 amino acids is chemically distinct and each can, in principle, occur at any position in a protein chain, there are 20 × 20 × 20 × 20 = 160, 000 different possible polypeptide chains four amino acids long, or 20n different possible polypeptide chains n amino acids long.
