How does the charge of a protein depend on its amino acid residues?
How does the charge of a protein depend on its amino acid residues?
By the abundance of basic amino acids
By the abundance of acidic amino acids
By the abundance of neutral amino acids
By the abundance of hydrophobic amino acids
Solution
A protein acquires charge depending on the abundance of amino acids residues with charged side chains. Histones, which are rich in basic amino acids lysine and arginine, have positive charges in their side chains.
