Which of the following pairs of amino acids represents a conservation of the type of amino acid when considering the sequence of a protein from different species?
A)Asp and Asn
B)Lys and His
C)Leu and Val
D)Gly and Ile
E)Phe and Trp

Question

Quizplus · Accepted Answer

Leu and Val are both hydrophobic amino acids with similar structures, making them likely to be conserved in proteins across species. Asp and Asn are both polar amino acids but have different functions and structures, making it less likely for them to be conserved. Lys and His have different charges and functions, making it unlikely for them to be conserved. Gly and Ile have very different structures and functions, making it unlikely for them to be conserved. Phe and Trp are both aromatic amino acids, but Trp has a larger bulky structure, making it less likely for it to be conserved.
