Histone proteins are rich in:
Correct answer: A. Basic amino acid
- A. Basic amino acid
- B. Acidic fatty acid
- C. Başic citric acid
- D. Acidic amino acid
Explanation
Basic amino acids are amino acids that have a positively charged side chain at physiological pH (around 7.4), due to the presence of an additional amino group (-NH₃⁺) in their side chains. These amino acids can accept protons (H⁺), making them basic.They are found in histones.
