Question
neutral-nonpolar amino acids acidic amino acids basic amino acids glycine (Gly, G) aspartic acid (Asp, D) glutamic acid (Glu, E) lysine (Lys, K) arginine (Arg, R) histidine (His, H) alanine (Ala, A) H-N-C-C CH H CH H CH2 H CH2 CH2 HC-C NH neutral-polar amino acids valine (Val, V) threonine (Thr, T) tyrosine (Tyr, Y) asparagine (Asn, N) glutamine (Gln, Q) isoleucine (Ser, S) H CH H CH2 H CH H CH2 H CH2 H3C CH H3C CH2 tryptophan (Trp, W) phenylalanine (Phe, F) proline (Pro, P) methionine (Met, M) leucine (Leu, L) cysteine (Cys, C) H CH2 H CH2Explanation / Answer
One pair is Alanine and valine as they are both hydrophobic amino acids and structure of both of them is similar and will have conservative mutation
Second pair is leucine and isoleucine and isoleucine has only extra CH3 and will have conservative mutation.
Third pair is aspartic acid and glutamic acid as they both are acidic amino acids and will have conservative mutation.
Fourth amino acid is lysine and arginine as they are basic amino acids and will have conservative mutation.
