just olya [345]

Answer:

D) yes, because both lysine and arginine are positively charged to the tertiary structure and therefore function should be similar.

Explanation:

The lysine, histidine and the arginine are positively charged amino acids as their pkA is higher and shows high affinity to bind the protons as a result of which they take positive charge.

The lysine amino acid is involved in the formation of the lysosomes and if a mutation in the gene which forms the lysosomes take place and lysine is substituted by the arginine then the mutant lysosomes will be as functional as the normal lysosomes.

Thus, Option-D is correct.
