QUESTION-1
ANSWER
The following amino acids would not be cleaved by chymotrypsin
b. B. K
EXPLANATION
Chymotrypsin cleaves following amino acids in their carboxy-terminal
Tyrosine - Y
Tryptophan- W
Phenylalanine- F
Methionine- M
So here lysine-K would not be cleaved by the chymotrypsin.
GOOD LUCK!!!!
