  2. Three letter code = Cys
  3. Codons = UGU, UGC
  4. It is a special case amino acid 

6

Name the Amino Acid shown below: 

Glutamic Acid 

Features

  1. Single letter code = E
  2. Three letter code = Glu
  3. Codons = GAG, GAA

7

Name the Amino Acid shown below: 

Glutamine 

Features

  1. Single letter code = Q
  2. Three letter code = Gln
  3. Codons = CAA, CAG
  4. It has a polar but uncharged side chain. 

8

Name the Amino Acid shown below: 

Glycine 

 

Features

  • Single letter code = G
  • Three letter code = Gly
  • Codons = GGU, GGC, GGA, GGG
